Good News! We have been working on porting Pocket Frogs to Android and a beta version is now available on the Google Play store. Data from the Mobage version is not recoverable.
We created the iOS version of Pocket Frogs and another company, Mobage, ported it to Android for us. In late 2015 they decided to remove our apps and several other apps from their platform. Only our apps that were previously ported by Mobage (Tiny Tower, Pocket Planes and Pocket Frogs) are affected. All others will remain on the Google Play store.
We have since re-released Tiny Tower on Android but the Mobage version data is non-transferrable.
