Everything Guitar Tuner Pro & Metronome can do
Supports 8 instruments
Acoustic and electric guitar, bass, ukulele, violin, banjo, mandolin and more — including 6-, 7- and 12-string configurations.
A truly professional tuner
Tune by ear too — play a reference note for any string and match it, or watch the needle settle into the green for a perfect pitch.
Practice with precision
A built-in metronome with a smooth BPM dial, tap tempo, 2/4 · 3/4 · 4/4 · 6/8 time signatures, and quarter, eighth, triplet and sixteenth subdivisions.
Multiple tuning modes
Standard, Drop D, Drop C, Half Step Down and more — or create your own custom tunings and fine-tune every string's frequency by hand.
Perfect sound every time
Fast, accurate pitch detection picks up your instrument instantly, so every string lands exactly where it should — on stage or on the couch.
Tune in your language
English, French, Russian, Spanish, Portuguese, Hindi, Chinese, Japanese and more — the whole app in the language you're most at home in.

Frequently asked
Is Guitar Tuner Pro free?
No — it's a premium one-time purchase. Pay once on the store and own every feature forever: no ads, no subscriptions, no in-app unlocks.
Which instruments can I tune?
Acoustic and electric guitar, bass, ukulele, violin, banjo, mandolin and more — with 6-, 7- and 12-string support and custom tunings for anything else.
Does it work offline?
Yes. Tuning uses your device's microphone and all pitch detection happens on the device, so it works anywhere — no connection needed.
Does the app record my audio?
No. The microphone is used only to detect pitch in real time. Audio is processed on your device and never recorded, stored or uploaded.
What can the metronome do?
Set any tempo with the dial or tap tempo, choose 2/4, 3/4, 4/4 or 6/8 time signatures, and practice with quarter, eighth, triplet or sixteenth subdivisions.
