Yet another chord reference app, for piano and/or guitar. Plentiful view system, that should be work well enough on all screen sizes.
Lets you find chords propriate to your skill level, preference or music style. Everybody will not be able to play perfectly, some prefer barre chords over simple few finger chords with only four thinnest strings.
Has a little less theoretic approach for chords and scales. Lets you dive into chords, without need to know anything from them. Piano or guitar, it does not matter. See how chords are formed, hear how they sound like. Learn, explore or be inspired.
One chord app to rule'em all.
