Even on Google Developer Console it would help if one could see the daily install/uninstall ratio - that would say more than trying to separate the increased downloads on a certain day from whether the desirability factor of the app is increasing.
Though agreed that the install/uninstall rate may not say anything specific about a certain day/version - since it could be uninstalls of a previous version or users cleaning out their phones.
If folks remember the slide in Google Developer Console download states from a month or so ago - my conclusion was that that was related to the launch of the Samsung Galaxy S4 - there was a corresponding slide in the Android 2.3.x phone active users - while a rise in the newest version …
Which suggested to me that it was related somehow to churn.
Also the Samsung Galaxy S3 numbers did not slide as much - but the Samsung Galaxy S2 numbers slid more - and so it could be that while S3 users were not as keen to upgrade, the S2 users may have thought the jump was worth it and so they may have bought the S4 … ?
Another thing Google needs to do is balance the rating number to more heavily skew recent ratings - this way apps which are “improving” are not forever shackled by their earlier faltering steps (when they were getting bad ratings etc.). Perhaps Google is not wanting developers to bother improving apps - but just make a new one. And that maybe a valid point.
