Start tuning

Open the app, choose guitar, pipa or ukulele, allow microphone access and pluck one string at a time in a quiet place.
Automatic string detection is on by default. You can also select a string manually.
The needle points left when the pitch is flat and right when it is sharp. Turn the tuning peg a little at a time and check once the sound stabilizes.
Open Settings to change the tuning, reference frequency and tuning tolerance. Tap a reference-tone button to compare by ear.

Frequently asked questions

Why is there no pitch reading?

Make sure microphone access is enabled under iOS Settings → Privacy & Security → Microphone. Move your device closer to your guitar, pipa or ukulele, pluck one string and reduce background noise. Listening pauses while a reference tone plays and resumes afterward.

Does “Target Pitch” mean the string is in tune?

No. When no sound is detected, the app shows the target pitch and the measured frequency remains “—”. Live results appear only after a sound is detected. A check mark on a string means it reached the target during the current tuning session.

What if automatic detection picks the wrong string?

Mute the other strings and pluck just one. If its pitch is far from the target, select the string manually and adjust gradually. For alternate tunings, set each string's target note in Settings first.

How do I buy or restore ad removal?

Open “Remove Ads” in the app's Settings to buy the annual auto-renewing subscription. The App Store purchase sheet shows the current price. If you already subscribed, use the same Apple Account and tap “Restore Purchases”. Ads are hidden while the subscription is active.

How do I cancel or request a refund?

Manage your subscription in iPhone Settings → your name → Subscriptions. Deleting the app does not cancel it. Apple handles refund requests at Report a Problem. See Apple's cancellation guide for instructions.

Is microphone audio uploaded?

No. Audio is analyzed on your device in real time and no recording is created. The ad service needs an internet connection and may process device, ad interaction and diagnostic data. See our Privacy Policy.
