Which is the more liked OS for Mobile? I mean what most users use. I am asking this because I am about to develop a mobile app so I want to know which OS to choose as base OS for my mobile app.

The most used OS is Android. As of in this year Android has became the largest used OS suppressing all other OS's including both desktop and mobile users.
