I have and Samsung S3 I just purchased and downloaded iScore through Google play, and just realized that it would be much better to use the App on my Kendal Fire. I check the store and it has it but I really don't plan to pay for it twice. IS there anyway to install it on my Kendal and keep my same account.?

Please help. Thanks.

Amazon requires that you purchase through the Amazon App Store for Kindle Fire devices. If they ever change the policy to allow you to install Google Play, then you would be able to install from there without a separate purchase.
