iOS app for BLE device - App project

Mobile app project description

So, we are building a smart lock controlled through bluetooth, and need to get iOS app designed for the same.
You can go through candyhouse.co/ august.com as a reference point to understand our project better.

Here you go with brief of basic features:

1. Automatic Connection establish on proximity with the lock
2. Get authenticated by sending passcode/ Maintaining connection
3. Send particular codes over bluetooth to the lock when certain buttons are pressed (Like Lock/ Unlock/ Add Phone/ Remove Phone/ Activate x feature/ Activate y feature)
4. Receive particular codes over bluetooth from the lock and display that information on the app

2-3 more Advanced features, + a web server feature, that we will discuss later. You quote the amount for this basic app.
