Don't even hesitate! – Chordial - Chord Dictionary Review
Honestly this app wraps it up so perfectly that I had to rate it immediately. Not only do you have an arsenal of chords and diagrams for 4 stringed instruments at your fingertips, but you can even preview the chord! I wouldn't even bother with any other app, especially if you plan on writing music on the go. Certainly a musicians best friend right here. Do see for yourself.
