Mobage has removed Pocket Frogs, Pocket Planes and Tiny Tower from the Google Play store and turned off the game servers on September 24th, 2015. Game play is no longer possible and all progress is permanently lost.
We have no current plans to port the iOS versions to Android. The iOS versions of these apps will still remain active but the data is not transferrable from the Android to iOS version. Future sequels or major updates could possibly support Android though.
For purchase related concerns please contact Mobage support at their website: http://support.mobage.com/ or via email at support@mobage.com.
