Pluck: free tuner for guitar, bass & ukulele

Play a string and Pluck shows whether you're flat, sharp or in tune. Tap a string to hear its note, switch between alternate tunings, or save your own.

Pluck is free, with no ads, accounts or tracking. Audio is analyzed on your phone and is never recorded or sent anywhere.

Tips

• No sound when tapping a string? Turn up the volume. Pluck pauses listening briefly while a note plays.
• Needle jumping around? Pluck one string at a time, a little away from noise, and let it ring.
• Microphone access: if you declined it, enable it in your phone's Settings › Pluck › Microphone.
