You know the song in G. The singer needs it in Bb. Capo tells you exactly where to clamp so the shapes you already know come out in the key you need. Most transposer apps hand you a new set of chords and leave you to relearn the song. Capo does the opposite: it keeps your fingers on the open shapes you already play and moves the capo instead. Spin two wheels, read the fret, play. WHAT YOU GET • Land on the right fret in seconds: pick the key you know and the key you need, and the capo fret (0–7) appears instantly • Play the song the easy way with open chord diagrams for the I, IV, V and vi shapes you will actually finger • Stop guessing what fits: all 24 major and minor keys with their full I–ii–iii–IV–V–vi chord families and relative keys • Walk on stage prepared: save every song with its key, capo fret and notes, then search and sort your saved songs by title, date or capo • Start playing tonight with five starter songs already in your songbook • Rehearse anywhere: everything works offline in the practice room, the church basement or the campfire PERFECT FOR • Singers and acoustic players who need a song in a different key before tonight • Worship and praise teams matching charts to each vocalist's range • Beginners who know four open chords and want to play many more songs • Songwriters and teachers testing which key sits best for a voice WHY NOT JUST LOOK IT UP? A chart on the wall shows one direction and none of your songs. Capo swaps the direction in a tap, shows the actual shapes to strum, and remembers the fret for every song in your set so you never re-solve the same problem twice. PRIVATE BY DEFAULT Your songbook stays on your device. No account, no sign-in, no ads and no tracking. Capo never needs an internet connection to do its job.
