Ukulele Tuner: Chord & Scale

Ukulele Tuner is a chromatic tuner built for the uke. Tap start, pluck one string near the microphone, and the needle slides to the note with the exact cents offset, so you can see at a glance whether you are sharp or flat before you touch a tuning peg. 🎵

It works fully offline. No account, no internet, no waiting.

HOW TUNING WORKS
Pick a string on screen, pluck it, and turn the peg until the dial centres and the string glows green with a gentle buzz. Tap any string to hear its reference tone if you would rather tune by ear. The chromatic engine reads whatever note it hears, so it also handles a string that is a long way off pitch.

FEATURES
• Real-time chromatic pitch detection through your microphone
• Large needle dial showing the detected note and the cents offset (±)
• The four ukulele strings as tappable targets that light up when in tune
• Tap a string to play its reference tone
• Standard GCEA ukulele tuning always included
• Haptic buzz the moment a string lands in tune
• Works entirely offline, with no sign-up
• Warm wood-grain design that is easy on the eyes

FOR EVERY UKE
Soprano, concert and tenor ukuleles all use standard GCEA tuning, which is included from the first launch. Baritone players and anyone tuning ukulele strings to low G or a slack-key voicing will find those in Pro. Whether it is your first C chord or a well-worn tenor, the tuner keeps up.

PRIVACY
Audio is analysed on your device in real time to detect pitch. It is never recorded, saved, or sent anywhere. The microphone is the only permission the app asks for.

GCEA TUNING — UKULELE STRING NOTES EXPLAINED

Standard ukulele tuning is G4-C4-E4-A4, known as GCEA. The G string (fourth string, closest to your face) is tuned high — it is a re-entrant tuning where the fourth string is higher than the third, which gives the ukulele its characteristic cheerful sound. Each string is shown on screen with its note; tap any string to hear the reference pitch for tuning by ear. The chromatic engine reads whatever pitch it hears, so it also catches a string that has drifted far from pitch and guides it back.

UKULELE TUNER FOR SOPRANO, CONCERT AND TENOR

Soprano, concert and tenor ukuleles all use standard GCEA tuning — the string lengths differ, but the notes are the same. Baritone ukulele uses DGBE tuning (the same as the top four strings of a guitar), which is in the Pro tier. Low G tuning replaces the re-entrant high G with a low G for a fuller, more guitar-like sound across the fingerboard — also in Pro, along with reference calibration from 432 to 446 Hz for playing alongside ensembles that tune away from standard A440.

LOW G VS HIGH G TUNING — WHICH TO CHOOSE

High G (re-entrant) gives the bright, twangy ukulele sound. Low G tuning drops the fourth string an octave for a fuller bass range, closer to guitar. Most beginners start on high G. Low G is popular for fingerpicking styles that need a wider range.
