Cloud Tuner

A minimal guitar tuner for six-string guitar with a retro pixel-art face. Most tuners show you a needle; Cloud Tuner draws the whole approach. Play a string and it follows you, plotting your pitch on a scrolling grid so you can see how you're moving, not just where you are. Get inside the lane, hold it for half a second, and the string locks in with a chime and stays marked while you work through the rest. Clear TUNE UP and TUNE DOWN guidance shows the exact offset in cents.

Tap a peg on the headstock to target one string instead of letting the app choose — and to hear its reference note, so you can tune by ear even without the microphone. A level meter beside the AUTO switch shows what the app is hearing. Supports standard, Drop D and Half Step Down tunings. Light and dark themes follow your phone.

Works completely offline. No account, no ads, no tracking. Audio is analysed on your device and never recorded or sent anywhere.
