The basics are free. The premium unlock adds the complete chord and scale collection, the progressions, and the song tools. Tap the upgrade button in the top corner, or open any locked feature, to see the premium screen and the current price.
New phone, or reinstalled the app? Open the premium screen and tap Restore Purchases. Your unlock comes back, tied to your Apple ID, with no second charge. You can confirm it in Settings, where an active unlock is marked with a green seal.
