My app has been in the App Store for 2 years and is top of its niche. We launched on Android 8 months ago and this is also going well. I want to take the app to the next level by learning from how my users (over 10k users per day) use the app. What do they press as soon as they open the app, why do they uninstall (or what were they doing right before uninstalling), how does a brand new user use the app (i.e. does he go straight to our tutorial or just dive in). Any suggestions on SDKs, websites, etc . . that would help me to track down and study this information would be appreciated.
