If you bought it through here you should have gotten the Android .apk file along with the purchase, you get that onto your Android device and open it up on that to install it as the full app. (There is no iPhone version.)
Is there a way to get that offer the other way around? I just bought it on the google store before I realized there is a PC version. It was my first android purchase in 5+ years, I enjoyed the demo so much.
