Have you ever wondered what are the best travel apps? I found an article which lists as much as 50 best mobile travel apps (in 2015). You can read it here: http://www.timeout.com/city-guides/trav ... avel-apps/
Basing on this article, the market can be divided into some categories:
- apps for planning
- and documenting a trip.
Can you think of other travel app categories?
