iPhone

Works out the chords of any song you play or import, and sets them above the lyrics. Everything runs on your phone — your music is never uploaded. Stop spending an evening working out a song by ear. Fretbook listens to an audio file on your phone — or to the instrument you're playing — and works out the chords. What you get back is a chart you can actually play from: chords sitting above the lyrics, right on the word where they change. WHAT IT DOES • Finds the chords — major, minor, 7ths and more • Detects the key and the tempo • Snaps chords to bar lines so the chart is playable on guitar • Transcribes the lyrics and places them under the chords • Shows guitar shapes and piano keys for every chord • Transpose and capo support — change key with one tap • Follows the chords as the track plays, and loops the hard part • Shares the chart as plain text BUILT FOR PLAYERS, NOT FOR DATA It produces a playable chart, not raw output. Chords land on the bar, out-of-key readings get corrected, and complex voicings are reduced to shapes you can hold. The raw result is still there if you want it. YOUR MUSIC STAYS ON YOUR PHONE Analysis happens entirely on device. Your songs are never uploaded to a server, and it works without a connection. HOW TO USE IT Import an audio file or play into the microphone. When the analysis finishes, the chord chart appears. To transcribe lyrics automatically you download the lyrics model once; you can also paste lyrics in yourself. You get 2 free analyses a day. Watch an ad to earn another, or go Pro to remove ads entirely and use it without limits. Pro is a one-time payment — there's no subscription. SUPPORTED FORMATS M4A, MP3, WAV, AIFF, CAF, FLAC. Protected tracks downloaded from Apple Music can't be opened.
