Peek behind popular apps
App analytics for indie developers
Trending apps · revenue estimates · why they moved — analytics for indie devs
Two questions for you
QUESTION 01
You open the App Store top chart. A name you don't recognise sits at the top. Why is it climbing? What changed? Nothing tells you.
Reveal the hidden reasons with data
QUESTION 02
