Simple and Effective
A great quick go to without too many distracting features, for songwriters needing quick reference. Highly worth the small purchase price.
Helpful app
It doesn't have some of the more complex chord forms for guitar, but it has all the basics and then a few. It'd be more helpful if it contained a reverse chord finder. It's easy to use and has fingerings for a variety of instruments.
Garbage - don’t waste your money
can't spell out nothing more than simple chords.
