Ratings and reviews

Excellent learning tool with too many ads. I love the learning material. I would very much like to pay a one time fee to get rid of the ads but the material and Duolingo like progressions are fantastic.

2nd time I went to use it, the ads had no way to skip. they just filled my screen. No thanks.

Exactly the app I needed to learn guitar theory - easy to use and learn from.
