Android is coming! We have an internal build that’s almost at parity with iOS but still needs a bit of tuning and is missing a few key features like Migrations. We’ll work to release & open-source it soon. You can register to be notified of that [0].
As good as Realm looks for iOS, I think it might be needed more in Android as there are no really viable alternatives other than using sql lite directly.
