Tap any fret on any string to play that note. Fret 0 is the open string — tap it to play the string with no finger on the neck.
Tilt your phone to shift the fretboard up or down the neck. Tilt one direction to move up, the opposite to move down. Return to center between tilts to move again.
Hold your finger on the screen after plucking a note, then tilt to shift frets. The fretboard becomes more responsive to tilt while you're touching the screen. Lift your finger when you're done moving.
Switch between Guitar, Bass, and Ukulele using the buttons at the top. Each has its own tuning, string count, and fret range.
Tap the Clean/Distorted button to toggle distortion on and off.
Tap the scope icon to recalibrate the tilt reference point. Use this if the fretboard starts drifting or after you change your grip.
