Where is my practice saved?
On your iPhone. There is no account or automatic cloud sync. Before deleting the app or moving to another device, open Settings and export a JSON backup to a safe location. Importing a backup replaces your current practice data after confirmation.
How do I restore my purchase?
Use Restore Purchases in Settings while signed into the Apple Account that made the purchase. An internet connection is needed to contact the App Store.
How does the accompaniment work?
Each key has the same four-bar major ii–V–I form: ii7, V7, Imaj7, Imaj7 at 90 BPM in 4/4. Pause or loop it during practice. Turn it off when the harmony does not fit your exercise.
Can I correct a practice entry?
Open History to edit the key, date or self-assessment. You can undo a completion during the current practice session. The app does not listen to or grade your playing.
What if I request a refund?
Apple handles payments and refund requests at reportaproblem.apple.com. Existing practice data, history and backups remain accessible if full access ends.
