This app is so simple and exactly what I need to compose my own simple backing tracks to play to. I want to figure out how to cast the screen to a television for teaching playing in a band or even improv in a group setting.

**Developer response:** Thanks so much for your review. We are working in new exciting updates!

### 5/5 — Useful app, responsive developer

*2021-12-29*

I got the free app a while back. Used it for a little while and then realized I really needed the full app. 

I bought it and it was still behaving like the free version. I emailed the developer and got a prompt response. 

Deleting and reinstalling did the trick. I’ve been using this with full functionality now. It’s been instructive for this intermediate guitarist.
