MAKE IT YOUR TUNER
Choose from seven distinctive visual skins, from clean minimal layouts to classic meter and modern studio designs. Your instrument, reference pitch, input, and appearance preferences stay saved on your device.

INTONATION CHECK — FREE PREVIEW
Use the guided six-string workflow to compare open and fretted notes, capture stable readings, and review cautious setup guidance. This preview is available without a purchase or account.

PRIVATE BY DESIGN
Microphone audio is analysed in memory on your device. The app does not save or upload recordings and contains no third-party advertising or analytics SDK. No account is required.

Guitar Tuner may load a first-party artist news or music promotion from guitar.sk. You can dismiss it, and no advertising identifier is used.

Whether you are practising at home, checking a guitar before a rehearsal, or reviewing intonation across the fretboard, Guitar Tuner keeps the essential feedback immediate and easy to read.
