I have an app I need a few people to test on their android devices. I've tested on kindle fire hd7 and motorola droid2. Works fine on both.

what i'm looking for is
1 does it work as expected on your device?
2 how useful do you think this app is for someone learning modes and scales? 1-10
3 improvement suggestions

testers will receive a free copy of the app obviously. also will be kept in mind for future projects that need testers.

thanks everyone,

reply here if interested
