The fret board is not realistic
Guitar player never looks at the fret board the way it is presented in this app. unless the guitar is hanging on the wall or lying on guitarist knees as a horizontal slide guitar. That is why visually the perception of the fret board is confusing and essentially not helping to develop the right skill. Other apps have more realistic presentation of the fret board in "perspective". Please make an option to change the fret board presentation.
In new version I like tapered guitar better, I would advice developer to keep working on the fret board presentation. Fret grouping is a little awkward. Should be 0-5, 5-7, 7-10, 10-12. Four stars for now.
