Put a capo on the third fret, play a G shape, and what everyone hears is a Bb. If the bass player or the keyboard player wants to play along, someone has to work that out. Capo Helper does it for you. Set the fret the capo is on and every chord is translated instantly, so the rest of the band knows what's actually sounding and the guitar player can use their capo as much as they want. It works the other way round too. Tell it what key the song is in and it will show you where to put the capo and which shapes to play. WHAT IT DOES • Translates every chord for any capo position, in both directions • Handles real chords — Am7, Csus4, F#m7b5, D/F# — not just root notes • Spells them correctly for the key: Bb in flat keys, A# in sharp keys • Finds the best capo position for a song's key, ranked by which frets give you open chords • Shows you how to actually play each chord with the capo where it is • Stage mode: oversized, high contrast, and the screen stays awake on a music stand CAPO HELPER PRO One purchase. No subscription. • Every alternate fingering for a chord, up and down the neck • Alternate tunings — Eb standard, Drop D, DADGAD, Open G and Open D • Partial capos, where each string can sit at its own fret • Bb, Eb and F transpositions for horns, plus a harmonica position finder • Nashville numbers No ads. No tracking. No account. No internet connection needed — all of it works offline. Bought Capo Helper years ago, when it cost a dollar? Tap Restore and Pro is yours. You already paid for it.
