About
Tune up, learn a chord and make time to play. Guitar Tuner by ChordChord brings tuning, chord discovery, lessons and jamming into one place.
TUNE YOUR INSTRUMENT
Use the microphone for automatic tuning, or play reference notes and tune by ear. Choose presets for acoustic and electric guitar, bass and ukulele. Adjust your reference pitch.
FIND YOUR NEXT CHORD
Search the chord library, hear a whole chord or an individual string, and save the shapes you want to practice. Explore alternative positions, switch between vertical and horizontal diagrams, and follow the colored finger guide.
MAKE PRACTICE A GAME
Try timed chord challenges, a ten-chord sprint or free practice. Strum along while the app listens: it recognizes C, D, E, G, A, Am, Dm and Em. It checks which chord you play, not your fingering. Microphone results depend on the instrument and your surroundings.
JAM IN YOUR KEY
Play along with 22 backing tracks across six genres. Change key and tempo, follow the chord shapes, and explore scale and chord tones across the neck. The scale TAB shows an ascending scale, rather than a transcription of the backing track.
KEEP THE TEMPO
Set your tempo, tap it in, choose accents and explore beat subdivisions. The metronome can keep playing in the background with system playback controls.
MADE FOR YOUR PRACTICE
Use it on iPhone and iPad, in light or dark appearance, with an interface available in 18 languages. No account is needed. Microphone audio is processed on your device and is not saved or uploaded by the app.
