Android-first and offline by design.

HarmonicGlyph is focused on local audio files and microphone analysis. The app is meant to work without sending music to a server.

Chords, sections, lyrics, stems, and reports.

Use it to inspect progressions, understand song form, and export the result as a PDF when you need a record.
