About this app

A guitar tuner and a metronome in one app. Play any string and the tuner finds it on its own, then shows how many cents sharp or flat you are. Open the metronome for a steady click from 30 to 240 BPM.

Tuning works fully offline. No sign-in, no account, and your audio never leaves the phone.

WHY THIS TUNER
• Real-time pitch detection, accurate to within a cent
• Automatic string detection: play any string and the app picks the right one, so you never tap to choose first
• A large, easy-to-read note and a smooth needle you can trust
• A clear "in tune" moment: green pulse, a soft chime and a short buzz, so you can keep your eyes on the fretboard
• Dark OLED screen that is easy on the eyes and easy on the battery

METRONOME
• 30 to 240 BPM, set with the steppers or by tapping the tempo you hear
• Beats per bar: 1, 2, 3, 4 or 6, with an accent on the first beat
• The click is scheduled on the audio clock, so the tempo holds steady instead of drifting
• Beat dots follow along, and the screen stays awake while it runs
• Runs offline. Opening the metronome releases the microphone, so the click never fights the tuner

INSTRUMENTS
• Guitar, standard EADGBE
• 7-string guitar, with the low B
• 12-string guitar
• Bass, 4-string
• Ukulele and baritone ukulele
• Violin, viola and cello
• Mandolin
• 5-string banjo, open G
• Chromatic mode for any note on any instrument
Every instrument above is included in the app.

ALTERNATE GUITAR TUNINGS
• Drop D
• DADGAD
• Open G
• Half step down (Eb)
Each one is a full preset with its own string chips, so you tune to it the way you tune to standard.

HALF-STEP TRANSPOSE
Shift any preset up or down by up to two semitones. Useful with a capo, or when you tune down for a heavier sound.

TUNE EVERY STRING
The app tracks each string as you go. A row of chips shows what is done and what is left, for example 3/6 on a six-string guitar. Reset any time to start over.

REFERENCE TONES
No quiet place to tune, or would rather not turn on the microphone? Tap any string to hear its exact pitch and tune by ear. The tones are synthesised to sound like a plucked string, so the app doubles as a pitch pipe.

CALIBRATION
Set your reference pitch anywhere from 432 Hz to 446 Hz. Standard 440 Hz is the default, and your choice is remembered.

LOOK AND FEEL
Amber is the default accent. Emerald, Ice Blue and Crimson are there if you want a different colour on the black screen. Vibration can be switched off in settings.

ABOUT THE ADS
The tuner never shows an ad. No banners, no pop-ups, nothing interrupting you while you tune or while the metronome runs. The only ad in the app is a short video you can choose to watch to unlock an alternate tuning or a colour theme, and that unlock is permanent. Skip it and everything above still works: every instrument, the metronome, chromatic mode, calibration, reference tones and the transpose. There are no in-app purchases.

FIVE LANGUAGES
English, Turkish, Spanish, Portuguese (Brazil) and German. The app follows your phone's language, or you can pick one yourself.

PRIVATE BY DESIGN
• No accounts, no sign-up, no tracking
• The microphone is used only to detect pitch, in real time, on your device
• Your audio is never recorded, saved or sent anywhere
• Tuning and the metronome work with no internet connection
