Bringing our apps to Android
We’re expanding to Android. The notes app A-Note and the list calculator A-CalcM are now in development for Android, and we’ve resumed development of the chord books G-Chord / P-Chord / U-Chord for Android. Release dates to be announced.
Apps
A-CalcM, A-Note, P-Chord, G-Chord and U-Chord will be updated in place — the apps you already have will evolve. Release dates to be announced.
Discontinued apps
These are no longer distributed on the App Store. Their pages remain for the support of people who already have them installed.
