I think you guys should put a little focus on the android tv app. I think you have a great iPhone app but the TV has a lot more real estate that you can add or port features to.

Think how many folks play the guitar in front the tv ?

I can think of lots of functionality including watching lessons , scroll tabs and more. Split screen views to play with friends , karaoke style or Add on and alike.

Again I think you have everything built for the phone app just need to bolster it for a tv screen.
