Frequently Asked Questions

• Q: Why can't I hear the metronome?

A: Make sure your device is not in silent mode (check the side switch on iPhone). The metronome uses audio playback that respects the silent switch.

• Q: The tuner is not detecting my instrument.

A: Ensure you have granted microphone permission. Go to Settings > GuitarTuna > Microphone and enable it. Also, try playing closer to your device's microphone.

• Q: I purchased a subscription but features are still locked.

A: Try tapping "Restore Purchases" in the subscription page. If the issue persists, ensure you're signed in with the same Apple ID used for the purchase.

• Q: How do I cancel my subscription?

A: Open Settings > Apple ID > Subscriptions > GuitarTuna > Cancel Subscription.

• Q: Does the app work offline?

A: Yes! Tuning, metronome, and chord library work completely offline. Internet is only needed for initial subscription verification.

• Q: How accurate is the tuner?

A: The tuner uses YIN-based autocorrelation pitch detection with sub-cent accuracy, suitable for professional use.
