You can create your own chord library, record the chords you have learned and mastered, and look through it anytime and anywhere.

The data is stored in iCloud, so you won't lose it even if you change your phone.

Custom Chords
You can customize your own chord presses and record all the chords you've learned.

Support single chord export, and generate pictures, print and share depending on your mood.
