Could be 5 star with UI updates
This app is free and does exactly what I was looking for. The fretboard exercises are great. The UI is terrible and I’m often stuck unable to press a lot of the notes that are near the edge of the screen which makes the app almost unusable. Would be great if we could rotate the orientation, or at least take the fretboard away from the edge, and maybe make the frets a little bigger. Otherwise, would be a 5-star app.
