It let me download it on my Fire, even though my Fire does not have a microphone. I tried using my headphones that have microphone capability, but the app doesn't recognize them so I can't do anything past lesson 1. I am far from happy considering I payed almost $20 for something that I can't use. If I could use it then maybe I'd love it. Bottom line: if you have a Fire or any other device that doesn't have a microphone then do NOT buy this. It's a waste of money.
