## What is Changes?

Changes turns a rough recording of your original song — a voice memo, a phone
take, a singer with a guitar — into a session-ready Nashville Number chart.

Number-chart apps make you type every chord. Audio chord-detectors hand you
chords to learn, not a chart to record from. Changes does the actual job, for
original and unpublished songs the catalog tools can't look up: play it in, get
the chart, fix it in a tap, and hand it off to Logic Pro.

HOW IT WORKS
• Record or import audio — a voice memo, a rehearsal take, or a quick pass on
  guitar. Rough and lo-fi is fine; that is what it is built for.
• Changes hears the key, tempo, and structure on-device, then works out the
  changes and lays them out as a clean Nashville Number chart.
• The bars it wasn't sure about are marked — tap any chord to pick what you
  actually played. Great draft, fix in taps.
• Tap the key to transpose the whole chart. Size the numbers for a music stand.
• Play along with a marker that follows the chart.

HAND IT OFF TO LOGIC PRO
Export a MIDI file, import it into your Logic template, and use Analyze chords →
Chord Track so the Session Players follow the changes. Export a PDF for the band.

PRIVATE BY DESIGN
Everything runs on your device — Apple's on-device Music Understanding, our chord
analysis, and on-device lyric transcription. Your audio is never uploaded. No
accounts, no analytics, no tracking.

FREE TO TRY
Record, chart, view, play along, transpose, organize your library, and save as many
songs as you like — free. Unlock Changes Pro once — buy it once, it's yours — for MIDI
export to Logic Pro and PDF chart export.

Requires iOS 27 (Apple's on-device Music Understanding ships in iOS 27).
Built for Logic Pro users: songwriters and artists cutting demos, producers,
session players, and worship music directors.
