Ukulele Tuner
Tune your ukulele (G C E A) with your microphone, including low-G, D and baritone tunings, with reference tones to tune by ear.
–
Tap “Start tuner”, allow the microphone, and play a string.
Tap a string to hear its reference note. With the tuner running, it follows whichever string you play.
- How it works
- Allow microphone access, then play one string (or note) at a time. The needle shows how far sharp or flat you are.
- Private
- Sound is analyzed on your device and never recorded, stored or sent anywhere.
How to tune a ukulele
- Start the tuner and play one open string at a time, letting it ring. Begin with the G string (nearest your chin).
- The tuner shows which string it hears. If the needle is left of center the string is flat — tighten it slightly. Right of center is sharp — loosen it.
- Always tune up to the note: if you go past it, drop below and come back up. The string holds its pitch better that way.
- When every string is in the green zone, play a chord you know and listen — then check each string once more, because tuning one string slightly changes the tension on the others.
