About Instrument Tuner
A clean, fast chromatic tuner that listens through your phone's microphone and shows the exact note you're playing in real time. Built for everyday tuning — guitar, ukulele, bass, violin and more — without the noise of cluttered apps.
★ How it works
Tap Start Tuning, play a string, and watch the note display update instantly. The needle meter shows whether you are flat, in tune, or sharp, and the cents readout tells you exactly how far off you are. When the note locks in, color and (optional) vibration confirm it.
★ Built-in instrument presets
- Guitar (standard E A D G B E)
- Guitar (Drop D)
- Ukulele (standard G C E A)
- Bass (4-string and 5-string)
- Violin, Viola, Cello
- Mandolin
- Chromatic mode for any instrument
★ Tuning details that matter
- Reference pitch options: 432, 438, 440, 442 and 444 Hz for orchestra and special tunings
- Sharp (♯) or flat (♭) note display, your choice
- Frequency in Hz, target frequency, and cents offset all visible at once
- String guide highlights which string you are closest to so you can tune one at a time
★ Designed to stay out of the way
- Works offline for tuning (no audio is uploaded)
- Light and dark themes follow your system
- Optional keep-screen-on while tuning
- Localized for players around the world
Whether you are warming up before practice, restringing your instrument, or playing in a band, this tuner gives you a quick, accurate read so you can get back to music.
