AndroLib estimates that just five paid-for Android apps have been bought more than 250,000 times.
Spacetime says its daily user activity on Android is more than double its level on iOS in practically every measure. On Android, the game is downloaded about 9,000 times a day, according to Spacetime; on iOS, daily downloads are in the 3,000 to 4,000 range. Perhaps even more significant, Android users who have the app use it about three times more than their Apple counterparts.
