My Pocket Ukulele Tuner
A ukulele tuner that names the note the moment you pluck it. Standard GCEA tuning, in high-G or low-G.
Common ukulele chord circles
A chord circle is four chords that sound good together in one key, played in a loop: I, vi, IV and V7. Countless songs use one. Start with C, the easiest key on a ukulele.
Strings run G, C, E, A from left to right, as you see them when you look at the fretboard. Numbers are fingers: 1 index, 2 middle, 3 ring, 4 pinky. A circle above a string means play it open. A bar means one finger presses several strings at once.
Tune up first: every chord sounds wrong on an out-of-tune uke.
Circle of C
C – Am – F – G7
Circle of G
G – Em – C – D7
Circle of F
F – Dm – B♭ – C7
Circle of D
D – Bm – G – A7

Questions
Is My Pocket Ukulele Tuner free?
Yes. The app is free to download and use. It shows a small banner ad, which is what keeps it free. There's no subscription or in-app purchase.
Should I use high-G or low-G?
Most ukuleles use high-G tuning, where the G string sounds higher than the C next to it. Some players fit a thicker low-G string for a deeper sound. Pick the one that matches your strings; the app remembers your choice.
