Top mobile app development companies report: app code optimization

Users ask for speed and small size apps, but with the latest technology and the best features a mobile app can offer them. To accomplish these users demands, mobile app development companies have to consider the app code optimization.

Mobile app code optimization is the process app development firms follow when working on improving the size and the speed of an application. These mobile app developers work on the code of the app project to reach the best performance using the less code possible.

On this new AppFutura report, some of the best mobile app development companies worldwide have shared their expertise and their procedures while working on mobile app code optimization as well as some thoughts about developing for iOS, Android, Native or Cross Platform apps.

The app developers that have collaborated are Techugo, Fluper, Applify, Consagous, IndiaNIC, Devodrome, Umbrella, Konstant Infosolutions, Grey Chain Technology, DevTechnosys and RAD4M.

THE APP SIZE

Users tend to check the app size before downloading a mobile app on their smartphone. This process allows users to predict and control the free storage space they have on their mobile phone. The app size is something that can help any mobile app development company because it will be a hint of the rate of success an app can have on a marketplace like Apple’s App Store or Google Play.

RAD4MRAD4MMobile app development company in Poland

Mobile application file size is significant. The less space it takes, the better because a user may have an insufficient amount of space on a device preventing them from downloading an application. Another problem with large app file sizes is the long time that it takes to download them. This may cause a user to opt out of downloading, so they are not going to experience your app because of this feature.

FluperFluperMobile app development company in United Arab Emirates

An experienced mobile app developer is well acknowledged with the fact that an application size matters a lot when planning out the app development strategy, too many features that expand an application size not only contribute towards raising the overall app development cost, but can prove detrimental since users often uninstall heavy files if they eat up too much of their storage space. Hence if your application size is increasing, then either discover ways to reduce the size or redefine your strategies to make sure your effort does not end up in the trash.

DevodromeDevodromeMobile app development company in Romania

The mobile app developer should keep the size of the app as small as possible. Both Google and Apple provide a lot of information related to how to develop smaller footprint apps. This plays an important role once the app is published because the users are more reluctant in downloading large and very large apps.

Consagous TechnologiesConsagous TechnologiesMobile app development company in United States

We do keep the app size in mind during the app development and strive to keep the app sizes down. We offer line item tasks for app size optimization on updates.

The average app file size is now 37.9MB for iOS mobile apps and 14.6MB for Android, but these average sizes can vary between different mobile app categories. For instance, a game app will naturally take up a chunk of the disk space as compared to weather, entertainment or social networking apps.

App size is of great importance because if it is too large it automatically becomes difficult and may also become expensive for users to download. To sum up, a big app size is going to demotivate people and reduce installs.

Being a user-centric digital company, our app developers are vigilant and always try to ensure that their app bundles are as small as possible. And that is why they go for lightweight SDKs or download content only when needed.

TechugoTechugoMobile app development company in India

The end-user is always concerned about the size of the mobile app, and users always prefer to skip the large app size apps. So, in order to make the app highly usable, you need to keep the app size, so the apps can work efficiently on low configuration mobile phones as well.

Konstant InfosolutionsKonstant InfosolutionsMobile app development company in United States

A large app size would demotivate users and reduce the number of downloads as it directly relates with the cellular download limit. Apple advocates the cellular download limit as 100 MB and it doesn’t let users download a larger sized app over 3G or 4G. There is a linear decline in the install conversion rate when it goes below the cellular limit. Therefore, we keep a check on the app’s size while developing apps at Konstant so that we can provide faster application performance to our clients and their customers.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

For performance reasons, the app size is one of the key parameters that should be taken care of at every stage of the app development. An app with less and optimized code works faster and more efficiently. Images/audio and video files play a big role in deciding the size of an app.

We have seen that startups are not too size focused as much as they are design focused, but product companies who focus on one product are looking to optimize the app for size.

On iOS, a consideration in the past was that >100 MB apps cannot be download over 3G/4G but very recently Apple has changed that to 150 MB.

We believe that with faster internet technologies like 5G on the horizon, size will stop becoming a concern in the coming year.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

The size of the app is important when we plan a new app and we always keep it in mind. The most important thing is to distribute the app’s resources correctly. Umbrella’s motto is to use the resources properly, think about their quality and optimize the app structure not forgetting about them.

ApplifyApplifyMobile app development company in United Kingdom

While installing an app of large size, users will have to spare a good amount of storage space and a huge chunk of mobile data. Nobody likes to do that. Hence, it’s preferred to keep the app size small so that more and more people download your app.

IndiaNICIndiaNICMobile app development company in India

The app size depends on the development pattern and architecture. So whatever development strategy you follow, it will eventually affect the size of the app. Sometimes the use of other third-party libraries also affect the size but we always keep in mind the application size on the development phase when moving resources, such as images, long strings, or tables, out of code and into external files, this will make the final download smaller.

DevTechnosys Pvt LtdDevTechnosys Pvt LtdMobile app development company in India

The high speed unlimited internet plans and increase in in-built memory size of mobile phones do not restrict the users to download the big applications if they are really worth to be downloaded, but still the app size is an important aspect and if we are considering it while planning the app development that will be really good because it impacts three main areas:

Downloads - The above scenario is not possible with all type of users and the user might need to look for Wi-Fi to download the big applications and also need to arrange more storage on their phones which is more difficult than to get Wi-Fi. They will not prefer to download the bigger applications and we are losing customers without letting them using our excellent application.

Uninstalls - If by any chance users have downloaded the application. if they are running out of space then they will first uninstall the applications taking more storage, and again, we will lose the customer in spite of providing a better application.

Performance – With limited space and poor connectivity, it will always be difficult to operate bigger applications.

So we will definitely suggest to keep the app size in mind while planning your app development.

THE APP SPEED

Once the app is downloaded, users, as well as clients, want speed. Waiting for a mobile app to charge is not something users are looking forward to do. Their interest is launching the app and using it straight away, and not waiting for it to charge. With good mobile code optimization, app development firms can improve the app speed.

DevTechnosys Pvt LtdDevTechnosys Pvt LtdMobile app development company in India

The app speed is an important aspect to take care while building a mobile application, there are applications in the market under every niche but the one with better performance is the one that will be popular. Losing the string with the users while our app is loading may prove to be fatal, as the users might think that the app is not functioning properly and taking lot of time to show relevant data. It also creates a negative impression in the user’s mind, hence giving them a bad user experience. So the app speed is really important.

RAD4MRAD4MMobile app development company in Poland

The app speed is one of the most important factors to consider when planning the app development strategy. People have very limited patience and will look for an app substitute if the app they are using is clumsy or slow. The research conducted by Google shows that 29% of smartphone users will start looking for a new application or a site if the one they are currently using turns out to be taking too much time to load or requires a lot of time to find the information they need.

FluperFluperMobile app development company in United Arab Emirates

This is an interrelated feature wherein the speed with which application loads can directly influence revenue earnings of the mobile app developer. So, yes application speed is important. The slower the application runs the less time the users are likely to spend navigating it, thereby resulting in the loss of potential users. Fewer conversions will result in less revenue generation. Few surveys reveal that the majority of users (63%) abandon an application if it takes more than 5 seconds to load.

DevodromeDevodromeMobile app development company in Romania

The speed of an app is of paramount importance. This is because a smooth app offers good user experience that keeps the current users and attracts new ones. Performance patterns are followed and applied during the design and development of the app. Render time for an app has to stay under 700 fps. Going over this value, the app will lag and a lot of ANR (Application Not Responding) pop-ups will show up on Android. Apple’s HIG has its set of rules. If an application is lagging, there is a high risk of not passing the review process.

Consagous TechnologiesConsagous TechnologiesMobile app development company in United States

App loading time beyond 10 seconds is inappropriate and also considered unacceptable by industry standards. We attach major significance to app speed because that determines user’s stickiness on the app, therefore if an app doesn’t load within 6 seconds, you will drive the user away and they’ll stop using it.

As app content becomes richer, and connections become faster, the factor of ‘immediacy’ - people wanting things instantly - has also picked up and is unlikely to reverse.

Therefore, to keep abandonment rates down, a swift app speed is essential.

TechugoTechugoMobile app development company in India

The app performance is also a vital element, since a slow app will always irritate users leading to instant uninstall. Although the app speed depends on many factors like the internet, coding style or development framework, it is highly important to consider each and every factor carefully while developing the mobile app.

Konstant InfosolutionsKonstant InfosolutionsMobile app development company in United States

“If speed thrills, friction kills.”

App speed and agility are the keys to a successful mobile app development strategy. And we hope each of the top app development companies agree on this. Millennials today are intolerant to low speed response and why won’t they be, when they have a myriad of options to choose from the app stores. People expect to navigate through a mobile experience at lightning speed.

App developers should actually invest their time to optimize, refactor and improve the speed of their apps. Use frequent iterations to get feedback on the speed. There are various performance monitoring tools that offer powerful diagnostics to tell you the times when your app slows down.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

App speed is based on a variety of factors, but the main ones that are appearing to the forefront are using Native vs Hybrid and what backend has been used.

Native is definitely faster compared to any hybrid technology and customers are looking for native rather than hybrid. We prefer to deliver everything in native and advise our clients to do so. Picking the right scalable backend is also very important for a high performing app.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

We can say that the app speed is more important than the app size. Because not every user pays the great attention to the app size, but for every user it’s important the app speed. Every app user will notice that the app is slow and won’t use it again. E.g Apple says that UX is much more important than the app’s functionality and the speed is the important part of UX.

ApplifyApplifyMobile app development company in United Kingdom

App speed is also important. People want things to happen in the blink of an eye. The same with mobile apps. If an app is slow, users will uninstall it within no time.

IndiaNICIndiaNICMobile app development company in India

Who loves sluggish apps? We don't like to use or even to build one app that runs slow and takes so much time to load. Performance is always a priority.

As we know, mobile apps depend largely on backend and internet connectivity, so if you’re rendering data over the network then you should have to minimize the network use and also render data with the minimal wait time.

TRICKS TO OPTIMIZE THE APP CODE AND MAKE IT FASTER

For mobile app development companies, to optimize an app is one of the most important jobs as it benefits the app user and the client. These app developers tend to have different tricks like working on optimization the code while developing the application or having just an specific team on optimizing the already developed code.

IndiaNICIndiaNICMobile app development company in India

Well, you might not fully optimize the code. Whatever time you spend, there is always more room for improvement to make your code run faster.

Optimization goals may be different, like optimizing the code for performance or for less memory footprint and size. You might have to find a balance. We take some time to think through and pick the right algorithm and architecture to use. Here’s a couple of examples,

Avoid unnecessary memory allocations, unused code and create objects only when required which save us the memory and improves the performance.

Analyze all of the assets your app uses, and determine which resources are required to add into bundle and group other infrequently used assets and put them onto the server which makes the final download smaller.

DevTechnosys Pvt LtdDevTechnosys Pvt LtdMobile app development company in India

There are many things which we can perform to optimize the app code:

Clean Code - Always try to write clean code which basically means:

  • Keep indentation low - Keep your indentation low when possible, separate logic into other methods and restructure when we can.
  • Practice good naming - Make a habit of properly naming the class, method, and all variables that you create while coding.
  • Proper commenting – Make proper commenting wherever required to clarify something.
  • Don’t leave dead code - Whenever you comment out existing code with the intent to delete it later, please do it immediately.
  • Less code Works better – Try to write small and effective code.

Loading data as per requirement - We can split the whole data into different pre-load/post-load blocks so that users can access at least some data by the time the whole page loads. Many app developers load the content first, and images at the end for the same reason.

Content and Images optimization

Caching

RAD4MRAD4MMobile app development company in Poland

We conduct a code review which we start with the static analysis of the code followed by refactoring and architecture modification. Then we perform unit tests. We also use tools to optimize our app code.

FluperFluperMobile app development company in United Arab Emirates

Optimization of the code involves two stages one is at the programmer end and the other is at the compiler end. So it depends upon the understanding of the language that the programmer is using to build the code and the communication with the compiler for the same. After the logic is implemented all the work to be done is on reducing the memory usage, rapid executions, and fewer input /output instructions. The optimization of the code doesn't come with a different person which can be passed onto the next stage and get done. The methodology for optimization may be developed by the programmer needs to be kept in mind while writing a code. So, Yes it takes pretty much the same time as it takes to code the entire application.

DevodromeDevodromeMobile app development company in Romania

Code optimization and performance optimization are not quite the same thing. Code optimization mainly means structured, component dependent, and easily expandable code. Performance optimization (faster app) means development (code design, algorithms, etc) that keeps the resources usage low (CPU, memory, battery, etc), smooth UI (user interface) and optimized background work. Normally, a cleaner code should perform better than a messy one. This mostly depends on the app specifics (size, complexity, resource demanding, objectives - e.g. battery life). It could only take a few hours, or even weeks of testing and tweaking (fine tunning).

Consagous TechnologiesConsagous TechnologiesMobile app development company in United States

We optimize the app code for enhancing app speed by not relying on too many external dependencies. This helps us keep the code simple and easy for other developers to grasp. Before we code, we acquaint ourselves with what the end result should be as app optimization will be ideal when we know everything before we begin.

We also steer clear of synchronous code because it can be difficult to understand when we have come so habitual of procedural operations. We basically employ tools, techniques and designs that take less time to implement.

The time we take to optimize app code depends on app’s complexity and nature. We also scan the code for memory leaks to verify the release and scope of objects.

TechugoTechugoMobile app development company in India

The optimization of the app code to make it faster depends on many factors such as backend coding, handling of all the runtime errors, front-end coding, and architecture, version of framework, database, etc.

The time frame for this depends on code standard, for instance: a small app consumes around 15 days, whereas a big app can take 1 month or more, depending on various factors.

Konstant InfosolutionsKonstant InfosolutionsMobile app development company in United States

In every phase of app development, we employ a host of expert strategies and skills to optimize the app so that it is faster-to-load. So, there are a couple of things that the mobile app developers keep in mind:

  • Loading data in chunks.
  • Images are kept in the S3 bucket and then recalled.
  • We give more emphasis on caching for images and data so that the app doesn’t lose the data when there is no internet.
  • Our app developers ensure optimization of API calls to reduce unnecessary load on the server.

We take up the optimization process post deployment, in an effort to reduce the time and energies that are otherwise exhausted when done in between the process. So, it only requires a couple of days to achieve a fully-optimized app.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

To make an app code work faster we execute the code in the main - thread. It gives the code a higher priority over the other codes that are executing normally. Being a high priority code, it will be the first one to execute followed by the execution of the other normal codes. Thereby, making it work faster.

Apart from this, we are building modular and scalable backends so that each one is optimized for the specific purpose it has been designed for.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

First of all, app developers need to use the asynchrony correctly. Asynchrony is the ability to work several processes simultaneously.

Secondly it’s important to make all animations work correctly and fast. How do we achieve it? There are a lot of tools that help us to optimize the app, Xcode highlights the suboptimal moments of the app which make the app work slowlier. Than we analyze these issues and change the code to optimize it. There are a lot of other services that help to notice this moments, e.g Facebook has also a similar Xcode tool.

About duration: it depends on the app’s features, but usually it takes about 10-20% of the whole mobile app development time. It doesn’t take so much time if it’s a recurring task and the app developer always does it. If the mobile app developer doesn’t do it in time, the problems sum up and it can take much more time to fix it rather than in a usual good managed workflow.

ApplifyApplifyMobile app development company in United Kingdom

We use app thinning for code optimization on iOS apps. The technique uses the combination of:

  • Bitcode, a special type of code: "LLVM Bitcode" is sent to iTunes Connect. This allows Apple to use certain calculations for re-optimizing apps further (e.g: possibly downsize executable sizes).
  • Slicing, a method used by Apple for modifying apps as per user device resolution and architecture. The technique doesn’t require Bitcode.

On the other hand, techniques like autoboxing, the OnDraw() function, and viewholders are used in Android.

TOOLS TO OPTIMIZE AN APP’S SPEED AND SIZE

For optimizing an application code, mobile app development companies have different tools. One of the most used ones is to reduce the amount of size images and to make use of Google’s Android Studio as well as Apple’s Xcode, which are softwares that improve speed and size of mobile apps.

ApplifyApplifyMobile app development company in United Kingdom

Using thumbnails instead of images reduces the app size up to a large extent. The app size is self optimized by XCode in iOS. You just need to enable Bitcode.

In Android, we use techniques like image rendering, crunching PNG files, use of binary code and vector graphics, etc.

Also, the app speed is optimised by caching. With this technique, we store values in cache instead of fetching data from server again and again. This makes apps work faster.

IndiaNICIndiaNICMobile app development company in India

Here are some of the tools we use for optimisation:

PMD is a static analysis tool, which helps us find common bugs in code like unnecessary creation of objects or unused variables which may become a hindrance in performance, even before executing the code.

The Hierarchy View is a tool bundled into the Android Device monitor. This tools gives us a hierarchical view of the layout, which helps in identifying the complexity of layouts, flattening those hierarchy increases when rendering of the layouts in screen.

Instruments is a performance-analysis and testing tool that ships with the Xcode and by using it we can easily check performance issues, CPU activity variation, memory allocation, reference cycles, network and file activity, and many other problems.

The Memory Profiler helps us check memory allocation for any leaks and churns. This tool provides us with real time graph by which we can address the problems like crashes, freezes and track memory warnings, and also force garbage collections.

DevTechnosys Pvt LtdDevTechnosys Pvt LtdMobile app development company in India

Yes, there are multiple tools that we generally use for optimization purpose like Akamai, Moblyzer, Newrelic, Xamarin test cloud.

RAD4MRAD4MMobile app development company in Poland

We use different tools depending on which platform (Android or iOS) we are working on.

Android

Genymotion – This tool helps us to react with the built-in sensors of the device model we are working on. We can interact with its battery charge level, check the quality of WIFI and GSM connection, as well as check the GPS location. Moreover, we can simulate receiving an SMS or call.

HierarchyViewer – A tool that enables us to view the tree of the app and analyze the app layout. Now we can optimize and debug the application. HierarchyViewer also lets us inspect the view tree pixel by pixel as it creates an image of our app's view tree. What is more, we use it for checking if there are any redundant layouts, which we can merge to increase the performance of the app.

LeakCanary – We think this tool is the best for detecting and tackling bugs. With LeakCanary we can be sure that no memory leak will escape our attention. We find it even more useful as it lets us know (sends notifications) about leaks that were detected so we can localize the bug and fix the problem before we get any OOM errors. This tool helps us save a lot of time and allows us to create a well-performing and high-quality app.

IOS

We use many app developer tools provided by Apple such as Instruments, Leaks, Profiler, and Allocations to check how iOS applications are performing. Thanks to them we can quickly check any performance or memory issues. We have an automated way of monitoring an app's performance, and we do it regularly by either running Instruments check periodically or doing Automated Performance Tests using XCTest framework.

FluperFluperMobile app development company in United Arab Emirates

Although there are tools available to reduce the size of an APK to reach the maximum customers, with a talented team of developers in Fluper we reduce the size of the APKs by different approaches using Support Libraries such as crunching PNG files, using vector graphics, reusing resources etc.

DevodromeDevodromeMobile app development company in Romania

An experienced app developer should be up to date regarding the newest performance patterns and best coding practices. Also, Google/Android Studio and Apple/Xcode provide options that can impact both the app size and speed. So, in our opinion no 3rd party tools are really needed, as long as the app developer is truly concerned about the app size and speed and have the necessary skills for achieving that.

Consagous TechnologiesConsagous TechnologiesMobile app development company in United States

For optimizing app speed we use Android Profiler and then we optimize images and the code structure manually

For optimizing app size we use ProGuard, Font Awesome for optimizing images and icon size, manual code structure optimization for reusability

TechugoTechugoMobile app development company in India

We use the tools offered by Apple and Android to check size and speed, they help us maintain the quality of our apps.

Konstant InfosolutionsKonstant InfosolutionsMobile app development company in United States

We use utility tools to compress the size of the images used in the app or that are loaded in the app either by users or admin. This puts the present code to test, which is then analyzed and compared with an optimized version, thereby removing the unused code, unused images from the present one.

For speed optimization, we keep showing the past data until there is any change in the API for fetching new data.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

Currently, the app optimization is being done at the code level by executing the same on the main thread. We do use some testing tools to check app performance like pCloudy which allows to test on thousands of devices in one common automated regression environment.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

For the speed optimization we use Xcode utilities and third-party tools as FB. As for the size optimization we use different conversion tools, there are many of them (both online and offline).

Also it’s always important to know how the programming languages work (e.g Objective-C and Swift and when these 2 languages are mixed) and their particular characteristic, the app developers need to know them as a default, if not, the tools won’t help them make a good working application.

DIFFERENCES BETWEEN OPTIMIZING APPS FOR iOS AND ANDROID

The two major operating system softwares, iOS and Android, have some differences among them. While Android has a very diversified amount of versions of its OS, Apple is known for boosting the implementation of its latest release of the iOS software. The differences between OSes for mobile app development companies is quite the biggest challenge when developing a mobile application.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

In fact, iOS and Android have a lot in common and the rules of app code optimization are the same. But each system has its own particularity and the app developers should keep them in mind. Android is on many types of mobile devices and it’s needed to keep in mind the specific things of all devices. And sometimes because of this fact the code optimization of Android apps can take a little bit more time than for iOS ones.

Each platform has small details that should be taken into consideration during the app development phase.

ApplifyApplifyMobile app development company in United Kingdom

The user interface is different on Android and iOS. Both platforms have their own guidelines. Although, the optimisation here is done in such a way that the user experience doesn’t get hampered.

IndiaNICIndiaNICMobile app development company in India

There is always more room for improvement. iOS and Android both run in separate environments. Both are different operating systems and have pros and cons, so the optimization depends on which specific architecture and design pattern is followed.

DevTechnosys Pvt LtdDevTechnosys Pvt LtdMobile app development company in India

Steps are common but while optimizing Android apps, we need to take care of many things:

Android phones are available in different layout and sizes and this poses a challenge for the app developers that while optimization, they need to test the application on every possible device. On the other hand, Apple has a limited device portfolio which can be tested easily.

Google does not encourage OEMs to use the latest version. This means that newly released phones might be using an older version of Android. Unlike Apple devices which always come with the latest iOS, Android devices could be running older versions. The availability of multiple versions of Android and the resulting OS fragmentation makes the optimization of the app code a challenging process.

RAD4MRAD4MMobile app development company in Poland

iOS and Android are independent platforms, so we have to use different tools for optimizing the app code.

iOS

Most importantly, Apple provides built-in tools in Xcode. The use of tools such as Instruments, Leaks, Profiler or Allocations helps significantly in obtaining efficient applications. To test application performance, we use XCTest framework. Thanks to this tool we can carry out unit tests, UI test and also automate tests and check application performance.

iOS programming environment is a great tool to work with because the whole platform is very well optimized. This fact helps to focus on the best practices of iOS programming and quickly results in good application performance along with small application size. Good application performance also ensures limited memory usage thanks to the selection of only those elements of the system that are essential to the operation of the app, proper memory management, and meaningful use of work on threads.

Android

In the case of this platform, the programming environment itself such as Android Studio is insufficient to create applications efficiently. Fortunately, there are many great applications which can be of use in this situation. One of them is Genymotion which enables us to test applications on various phone models. Another one, LeakCanary helps us detect errors and memory leaks. When working with Android environment, we have to focus our attention more on memory management and leaks, because Android system is not as stable as iOS.

One thing that these two platforms have in common is the best practices. Always when we are creating app code, the best practices help us reduce the number of occurring errors.

FluperFluperMobile app development company in United Arab Emirates

Yes, there are notable differences between iOS and Android, when it comes to optimizing applications.

One of the major reason is that Android is an open source platform but is capable of running across all hardware which makes it difficult to optimize for any specific hardware. Wherein Apple designs their own ARM CPUs that work faster than the ones used in Android devices. Android has proved to be the most vulnerable as software packages get easily modified and re-released. A kernel can be easily modified but Apple is highly strict with its policies and that is the reason why it is more secure. Many lower-end phones have phishing apps in the name of bloatware.

DevodromeDevodromeMobile app development company in Romania

The differences lie in the operating system, SDK, programming language and hardware architecture. So, the apps have to be treated separately.

Consagous TechnologiesConsagous TechnologiesMobile app development company in United States

The differences between optimizing apps for iOS and Android are marked on the following lines of development:

Programming languages

For Android app development the most commonly used language is Java, which happens to be a different version of the language for this purpose. Another one is C++ and the recent one, Kotlin, which was added as an official Android language being compatible with the other ones.

iOS programmers have been using Objective – C and Swift was introduced as the official language for iOS apps. Swift has been built for this sole purpose, for helping developers to build mobile apps that run on Apple devices.

Swift developers need to write less code, and it is likely for apps to appear faster than coding when Java is involved.

Development tools

For Android development, Eclipse was used at the beginning, but with the launch of Android Studio created by Google, the support for Eclipse ended so all mobile app developers who want to build Android apps are using Android Studio now. For iOS apps, a developer will use XCode, which is also referred to as the center of the Apple development experience.

Android has a built-in background compilation, allowing to highlight issues quickly whereas XCode needs an explicit build stage.

Development costs

Android development is known to be more time consuming as more code needs to be written compared to Swift. Segmentation is present only on devices with an Android OS, so a bigger device range increases the testing hours and the number of potential bugs to be fixed. In IT industry more time-consuming means more expensive, so it goes without saying that the same application for iOS costs 30% less than it does for Android.

TechugoTechugoMobile app development company in India

The optimization of Android and iOS is the same for image compression, database techniques, error handling, HTTP protocol, security and authentication, only the code structure is different.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

Optimizing any app code depends mainly on how well the code is written and the types of files used. On Android, its important to optimize apps for certain devices, like we have realized that on some particular brands of devices Android gives a lot more exceptions.

DIFFERENCES BETWEEN OPTIMIZING APP CODE FOR NATIVE AND CROSS PLATFORM APPS

With the possibility to work on native and cross platform apps, mobile app development firms have the chance to choose between developing an app optimized for a native platform or using the code to work on different platforms (cross platform app development). The app code optimization, as these mobile app development companies explain, has some differences.

Grey Chain TechnologyGrey Chain TechnologyMobile app development company in India

Optimizing the code of native apps is much easier when compared to that of cross platform apps. Unlike cross platform apps, in native apps the code is developed for one specific platform and hence, optimizing it becomes hassle free and easier. We take it on us to educate our customers on the benefits of using native technologies so that they are very aware and can then decide on what to go for.

Umbrella AllianceUmbrella AllianceMobile app development company in Russia

There are some differences between native and cross platform app code optimization, because cross platform apps are in fact web apps, but converted into mobile. Because of this, all cross platform apps are bigger in size and work a little bit slower than native ones. So far there is no method to make cross platform apps to be optimized as native ones and there you can find the difference. So we can say that native applications code is easier to optimize.

ApplifyApplifyMobile app development company in United Kingdom

We believe optimising native apps is easier because only one platform has to be kept in mind.

On the other hand, while optimising a cross platform app, the user interface of both the platforms has to be taken into consideration. Some functions that are working on Android may not work well on iOS.

Moreover, the code optimisation techniques are different on each platform. It can get tedious after a while.

IndiaNICIndiaNICMobile app development company in India

It is easier to optimize on cross platform apps as optimizing code at one place will directly affect all the platforms. So a change at one place will directly reflect at the rest. You don't need to spend twice the time for the same work. But there are certain limitations in cross platform app development that can be overcomed in native app development.

Native apps are easy to optimize as we can optimize them as per the required platform so it's always easy to implement the required options, but with cross platform apps, as its the same source code, it’s easier to optimize the app code.

Cross platform apps are more difficult to optimize because they have to be tested on different computing environments while when coding native platform apps we can focus on only one platform. Native applications also need fewer tests to check their readiness to use, and while writing their code, we are confident that it will match the platform we are writing on.

On the other hand, the code written on cross platform is harder to optimize, because one copy of it is compiled on many platforms what can cause problems. The degree of optimization also depends on the compiler which converts the code to a new code specific to given platform.

Optimizing the code for native apps is definitely easier because the focus is totally on one platform and the memory and power management can be efficiently done, whereas the cross platform is a blend of programming languages for multiple platforms and it's hard to meet the optimization requirements.

It is definitely easier to optimize a native app. The main reason is the app developer has full control over the written code. On the other hand, if during the mobile app development we face any cross platform framework slow performance (or limitation), it will be way harder (even close to impossible) to make improvements.

Optimizing code for a cross platform app is easier than doing so for a native app because native app development requires more time, investment in hiring additional and specialist app developers and the combination of all this leads to doubling or tripling the overall budget.

On the contrary, cross platform apps are time saving, affordable and the reduced development costs along with exposure across multiple markets leads to profit maximization.

Hybrid app development is much about JS and HMTL5 and thus, a change in jQuery is reflected on both iOS and Android platforms, which ultimately reduces the efforts and time consumed. On the contrary, when we work with native apps, app code optimization is a more complex process as the app developers need to endow much of their energy, brains and time to optimize the iOS and Android code separately.

But, of course, this doesn’t prevent us from developing native apps. We love to do both.

CONCLUSION

Users and clients want smaller apps in size while having the best speed and functionalities possible. This has become one of the major interests for mobile app development companies.

App code optimization has improved drastically since the first version of the different app stores available. Despite the increasing storage space on smartphones, users still look with precaution the app size before downloading a mobile app.
