OPEN. PLAY. ADJUST.

See what the string is doing.

The live meter shows how far the note is from pitch. The trace keeps each adjustment visible instead of replacing it with the next jump.

THE WHOLE FLOW

Listen. Show. Get out of the way.

No lesson plan, feed, login, or paywall stands between the instrument and the tuner.

Play one note

Allow microphone access and play a sustained note near the iPhone or iPad.

Read the pitch

The app names the nearest note and shows whether the pitch is flat or sharp.

Adjust and play

Turn the peg until the center lights green, then move on to the next string.

WHAT IS INCLUDED

A tuner, with the useful details left in.

ANY CHROMATIC NOTE

Let the app find the note.

Automatic chromatic detection works across the tuner range. Instrument presets make the expected open strings easier to pick out.

ANOTHER REFERENCE

Match the room you are playing in.

Set A4 anywhere from 430 to 450 Hz when an ensemble or another instrument uses a reference other than 440 Hz.

A CALMER METER

See the change, not only the latest reading.

The pitch trace moves upward over time. Your adjustments enter at the bottom so you can see whether the note is settling.

PRIVATE BY DEFAULT

Keep microphone audio on the device.

The app analyzes audio in memory while it is open. It does not record or upload the microphone signal. Optional product analytics stay off until you enable them.
