ChordU has two version of chords, It's highly mobile friendly & has capo tuner.
Not bad app... not always accurate... but good app!
YouTube integration makes it the easiest to use. It's otherwise very similar in functionality to Riffstation only no install needed. The ads can get in the way but the features still shine.
