All 108 guitar chords on one page, and a page for each — start with these four.
Guitar & Ukulele Chords
216 chord pages and 48 key pages. Every chord is drawn, played aloud when you press it, shown in its other shapes up the neck — and each has a microphone check: hold the chord on your own instrument, pluck the strings one at a time, and the page tells you which one is wrong.

Before the chords: tune it
A chord shape is only right on strings that are in tune. The guitar tuner and ukulele tuner listen through the microphone, and the tuning pages give the notes and frequencies of every common tuning, with the chord shapes that go with each.
