Mobile UI Analytics Tools and A/B testing

Hi guys,

I am working on a mobile game and I would appreciate some information on the tool you are using to measure:

  • MAU
  • player engagement
  • retention
  • how the users interact with the user interface

Also, how do you do A/B testing of the UI? Could you recommend a good tool?

Are these tools free or if not, how much do they cost per month?

Thanks!

GameAnalytics is free and pretty well used.
