Gong Logic

Pocket Fretboard turns your phone into a playable guitar — hold a chord, strum it, and learn the neck as you go.

PLAY LIKE A REAL GUITAR
• Hold strings down on the fretboard, then strum across the body to sound them — just like the real thing.
• Pick individual strings, or swipe to strum up and down with natural dynamics.
• One-tap chords — C, G, D, Em, Am, E, A, F and more — fretted and ready to strum.

LEARN AS YOU PLAY
• Every chord shows a finger-by-finger diagram: which finger, which fret, and which strings to skip.
• A piano keyboard below lights up the exact notes you're playing, linking each fret position to a real note.
• Press any string to hear its note and see where it lives on the keys.

PRACTICE TOOLS
• Built-in strum-pattern trainer with a metronome — play along to All Down, Folk, Pop and Ballad patterns.
• Capo support, so you can play in any key with the same shapes.
• Left-handed mode.

No setup, no sign-in — just pick it up and play.
