Switch between staff notation, numbered notation and falling notes. Choose left/right hand display and adjust practice speed. Play, pause and seek through a piece, or practice target notes in Follow mode. Save performance key events locally, play them back and export MIDI. Choose English, Simplified Chinese or Traditional Chinese. Membership is required for piano play, song practice and MIDI import. Choose a monthly or annual auto-renewable subscription; prices and billing periods are shown before purchase. A 3-day free trial is available to eligible new subscribers when offered by the App Store. Payment is charged to your Apple account.
