From iPhone to Android

[MossRatt]

I've changed phones from iPhone to Android and would like to know if I have to purchase the app again? I had the paid version with the iPhone and have noticed adds on the Android, plus it recommends I purchase the app.  Is there a way to transfer over the purchase or do I need to buy it again?  Great app BTW,  one of the best
