The tuner isn't picking up my instrument.
Make sure microphone access is turned on: open the iOS Settings app → Intonia → Microphone. Then hold the phone within a foot or so of the instrument and bow or pluck a single, sustained note.
Which instruments does it work with?
Intonia is tuned for the violin's four strings (G, D, A, E) and shows the nearest note plus how many cents sharp or flat you are. The chromatic detection also responds to viola, cello, and other pitched instruments.
What is the drone for?
The drone plays a steady reference pitch so you can tune your ear and match your intonation by sound, not just by the meter. Pick a string and press play.
What do I get with Pro?
The tuner, drone, metronome, practice streak, two guided exercises a day, and your practice history are free forever. Pro adds unlimited guided exercises, the full scale and arpeggio library, advanced insights, and home-screen widgets.
How do I manage or cancel a subscription?
Subscriptions are handled by Apple. On your device, open Settings → tap your name → Subscriptions → Intonia, where you can change or cancel at any time.
How do I restore a purchase on a new device?
Open Intonia, go to the paywall or Settings, and tap Restore Purchases while signed in to the same Apple ID you bought with.
