Filthy Tone

Precision That Slays

Our tuner cuts through the noise like a distorted solo. Pinpoint accuracy so your strings hit exactly right—zero excuses for being out of tune on stage.

Lightning Fast

No more fumbling between songs. Open, tune, rock. Works faster than a double-kick pedal at 200 BPM. Your audience waits for no one.

Dark Mode Native

Built in the shadows for the shadows. Pure dark theme that's easy on your eyes when you're burning the midnight oil in dimly lit venues.

Chromatic Devilry

From drop C to open G, from standard to that weird tuning your guitarist insists on—we support all of them. No questions asked.

Hear the Difference

Visual tuning is great, but sometimes you need to hear it. Let your ears join the dark side with our pitch reference feature.

No Sign-Up. No BS.

Download, install, tune. No account, no subscription, no soul-selling. Your email stays yours. The only thing we want is your devotion to the riff.
