of all, great idea for an app! I'm a hard of hearing music enthusiast and I can see myself using it daily when my hearing aid is off. Just a few things I'd like to see fixed: 1. The phone turns off after a few minutes which stops the music & vibes prematurely. 2. I have a lot of music files stored on my phone so it's a pain having to scroll down to pick the one I want, I'd like to see better library selection (sort by date, artist, album, etc). 3. Pressing any of the buttons on the phone immediately exit out of the app. This is annoying because my button are flat and I always accidently brush over them which kills the app a lot. If you can get these fixed, I'll update my rating to 5 stars.
