About this app

Chromatic Tuner is a clean, accurate tuner for guitar, bass, and ukulele. Play a string, watch the needle, and see exactly how many cents sharp or flat you are.

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

WHY THIS TUNER
• Real-time pitch detection, accurate down to about one cent
• 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

INSTRUMENTS
• Guitar, standard EADGBE tuning
• Bass, 4-string
• Ukulele
• Chromatic mode for any note on any instrument

TUNE EVERY STRING
Pick your instrument and the app tracks each string as you go. A simple row of chips shows what is done and what is left, for example 3/6 on a six-string guitar, so you always know how far you have to go. 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.

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

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 ads and no in-app purchases
• 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
• Works with no internet connection

Chromatic Tuner does one job well: getting your instrument in tune quickly. You choose the instrument and the reference pitch. The app listens and shows you where you are.
