01 / Tuner

Pluck a string. Watch the needle.

In automatic mode, the tuner recognizes the string you play. In manual mode, you pick the string yourself. Tap a string to hear the note it should play.

  1. Choose your instrument

    Guitar, bass or ukulele, in standard tuning or one of dozens of alternate tunings.

  2. Play one string

    Pluck it and let it ring. The needle shows whether the note is too low or too high.

  3. Turn the peg

    Tighten the string to raise the note, loosen it to lower the note, until the app marks the string as tuned. Then move to the next one.

02 / Guitar lessons

Lessons that listen as you play.

Short guitar lessons take you from your first open strings to barre chords. The app listens through the microphone and tells you when a chord rings right.

Em, A, E, Am, C, D, G and your first barre chords: each chord comes with a diagram, a sound to copy and a short exercise.
