Capoflip
iOS Universel / Musique
Capoflip is the single-purpose chord-chart tool every guitar and ukulele player wishes their songbook came with: paste a chord chart in any key, pick the key you can actually sing in, and Capoflip tells you exactly where to put your capo so the chords land on easy open shapes.
WHY CAPOFLIP
- That random chord chart you found has an F#m and a C#m and you cannot play it. Capoflip moves the song to a fingering position you can actually finger.
- "Use a capo" advice is everywhere; "use a capo on THIS specific fret because your chart has THESE specific chords" is not.
- One-tap transpose with proper enharmonic spelling. Capoflip writes Eb (not D#) in a flat key, and F# (not Gb) in a sharp key - the way a real songbook does.
HOW IT WORKS
- Paste any chord chart. Capoflip's parser handles both [bracketed] chord syntax and the classic "chord names above lyric lines" layout. It will not mistake "A bird flew by" for an A-major chord.
- Capoflip detects the original key from the chord set. Tap the +/- buttons to transpose to any new key, or pick from the row of key chips. Every chord on the page updates in place.
- Hit Suggest Capo Positions and Capoflip ranks the top three capo placements by how many of your transposed chords land on easy open shapes. Lower frets win ties (so you do not park the capo on fret 9 when fret 2 works).
WHAT YOU GET
- Side-by-side original + transposed chart view, with the chord names highlighted inline so you can still see where they sit over the lyrics.
- Tap any chord to see its fingering diagram, with finger numbers, on guitar or ukulele.
- 8 public-domain song charts to play with right away: Amazing Grace, Twinkle Twinkle, House of the Rising Sun, Scarborough Fair, Swing Low Sweet Chariot, Oh Shenandoah, Danny Boy, and Wayfaring Stranger.
- A bundled fingering library of 40+ guitar shapes and 20+ ukulele shapes covering every common chord quality (major, minor, 7, maj7, m7, sus2, sus4, add9).
- History tab - save the charts you transpose, mark favorites, jump back into any of them in their last-used key.
- Instrument toggle in Settings: switch between guitar (6 strings, EADGBe) and ukulele (4 strings, GCEA) and the capo recommender uses the right open-chord set automatically.
PRIVATE BY DESIGN
Capoflip has no account, no ads, no analytics, no tracking, no subscription, and no developer backend. The chord parser, the transposer, the capo engine, the fingering library, and your saved charts all live on your device and stay there. The PrivacyInfo manifest declares only the standard UserDefaults reason code required for local preferences.
