Uku - Ukulele Tuner
Chord Practice & Metronome
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Uku is a ukulele tuner that does one thing, quietly: it listens to your pitch in real time, so tuning disappears and playing can begin.
TUNE INSTANTLY
Real-time pitch detection built on the YIN algorithm locks onto your ukulele's tone the moment you pluck a string — accurate even with harmonic-rich, complex tones.
FOUR TUNINGS
Standard (High G), Low G, Baritone, and D Tuning (Canadian) — switch with one tap.
BUILT-IN METRONOME — NEW IN 1.1
Freely adjustable from 30 to 250 BPM, 1 to 9 beats per measure, per-beat accents, and subdivision up to 4-way, so you can build a steady sense of rhythm.
CHORD LOOKUP
Major, minor, dominant 7th, major 7th, and minor 7th chords for all seven natural roots — check a shape mid-practice without leaving the app.
SIMPLE, HONEST PRICING
Try Uku free, then unlock it once — no subscriptions, and every future update is included.
Uku doesn't need an account, doesn't track you, and doesn't get in your way. Just you, your ukulele, and the music.

• Chord Practice now shows which finger goes where: each dot carries a finger number, and a short list under the diagram gives the string and fret for every finger.
• Tap a chord name (Chord Practice) or a chord diagram (Chord Lookup) to hear the chord name read aloud in English.
• The three level cards in Chord Practice are now the same size.
