Common questions
- Is this a subscription or a one-time payment?
- One-time only. Pay once and keep the full practice studio forever — no renewal, no recurring charge.
- What does Follow Mode actually do?
- When Follow Mode is on, the sheet music plays one note then stops. It listens through your microphone and resumes only when you play the matching pitch. It trains ear–finger coordination note by note.
- How does Challenge Mode work?
- Press Challenge and a countdown begins. Then play the tune from start to finish. Every beat window is tracked — the app scores your run as a percentage of notes hit and saves an audio recording you can replay on the sheet.
- Do I need to sign in to use the free features?
- No. Browsing songs, viewing sheet music, and using playback controls work without an account. An account is only required to purchase membership.
