Guitar tools that just work
Tune your guitar, bass or ukulele with the microphone, keep time with a metronome, find the tempo of a song by tapping, play along with a drum machine or work out where to put the capo — all free, right here in your browser, with no sign-up and nothing to install.
Every tool runs on your device: the tuner listens through the microphone but the sound never leaves your computer or phone. They work on desktop and mobile, in light and dark mode.
These tools keep you in tune and in time. To actually get better, the FRET app for iPhone adds a coach, a band and a studio: guided practice sessions that remember your progress, jam tracks in any key, ear and fretboard training, a recorder that loops and slows down the hard part, and a strobe tuner precise enough for intonation.
