There is not a way to transfer purchases between these two app stores, but if you purchased on Amazon and you now want to install the app on your Google Play device, you have a two options:
- The easiest option is to install the Amazon App Store on your Android device. You can then install your purchased Amazon apps on your Android phone or tablet.
- If you prefer Google Play to install and update your apps, email me your Amazon receipt and I can send you a coupon code for a free copy from Google Play.
If you purchased on Google Play and you want to transfer that purchase to Amazon, unfortunately there is not a way to do that. You must purchase a new copy from Amazon. If you want your Google Play purchase refunded, please see how to refund purchases.
