Chromatic Tuner - Easy Tuner

Tune Smarter. Play Better.
Chromatic Tuner is a minimalist yet powerful tuner app built for musicians who demand precision. Whether you're a guitarist, bassist, violinist, cellist, flutist, vocalist, or any other instrumentalist — Chromatic Tuner gives you fast, accurate pitch detection in real-time.
Designed with a clean, distraction-free interface and studio-grade accuracy, Chromatic Tuner is the only tuner you'll ever need.
PRECISION TUNING
Chromatic Tuner detects pitch instantly using your device's built-in microphone. The high-sensitivity chromatic engine supports every note across all instruments — from the lowest bass strings to the highest vocal harmonics. No matter what you play, you'll always be perfectly in tune.
CENT METER
Fine-tuning matters. The intuitive cent deviation display shows exactly how sharp or flat you are, with a smooth, responsive needle animation that makes micro-adjustments fast and effortless.
SPECTRUM ANALYZER
See your sound, not just hear it. The built-in real-time spectrum analyzer (RTA, log scale) gives you a visual representation of your instrument's frequency content — a powerful tool for understanding your tone and environment.
REFERENCE PITCH
Customize your A4 reference frequency anywhere from 435 Hz to 445 Hz. Perfect for orchestral players, period instrument ensembles, or anyone tuning to a non-standard pitch.
REFERENCE TONE PLAYBACK
Need a reference note? Chromatic Tuner generates a pure reference tone so you can tune by ear — great for training your pitch recognition over time.
BUILT FOR EVERY MUSICIAN
Guitarists & bassists, violinists & string players, flutists & wind players, pianists, vocalists, ukulele, mandolin & folk instruments — Chromatic Tuner works for all of them.
