Music analysis for iPhone and iPad
Your music, analysed and organised.

With Pro, write your own lyrics and notes and export audio copies with lyrics and artwork.
Supported formats: AAC, AIF, AIFF, CAF, FLAC, M4A, MP3, WAV

Lyrics and notes
Your lyrics. Your ideas. At the right moment.
Save your lyrics, mark their lines while you listen and write down your ideas with optional timestamps. New in 1.5.0: lyrics already embedded in compatible files are read automatically.
New: embedded lyricsFree
- TrackScope reads lyrics embedded in compatible files automatically.
- Viewing them is free.
- Lyrics you edited in TrackScope take priority over the embedded ones.
- With Pro, export an audio copy with the active lyrics, or with lyrics and artwork together.
LyricsPro
- Paste, save and edit lyrics you provide.
- Mark line timings while the song plays.
- Follow the synced lines during playback.
- Use local timing suggestions when available, and complete or correct marks by hand.
NotesPro
- Save several notes about the song or its analysis.
- Optionally add a timestamp.
- Jump to that moment in the audio from a note, when the file is available.
- Improved: play the song from the notes screen and sort notes by position or creation date.
- TrackScope reads lyrics from file metadata or from what you type. There is no internet lyrics search, no automatic transcription and no word-by-word karaoke.
- Timing suggestions may be incomplete; perfect automatic sync is not promised.
- Notes belong to the song as a whole and always stay inside TrackScope.
- Saved text can be read even if the original audio is unavailable.
- Creating or editing lyrics, timings and notes requires Pro.

Artwork, folders and export
The same workflow, now with your library in order.
Analysis is still the heart of TrackScope. Artwork, folders, playback and export build on it, inside the same app and on your device.
ArtworkFree
- Artwork embedded in your tracks is shown automatically.
- Visible in the library, the analysis and the system playback controls.
- Choose an image from Photos or Files, adjust a square crop, preview and save.
- Change it again or restore the original artwork.
- Your customization is saved in TrackScope; the original file is not modified.
- Pro: export the artwork as JPEG or PNG, or create an audio copy with it embedded.
FoldersFree
- Create, rename and delete folders for albums, projects, references or works in progress.
- Add a track to several folders — it stays one track with one set of data.
- Organize several tracks at once with multiple selection.
- Browse “All Tracks” and “Ungrouped”.
- Each folder keeps its own track order; import straight into the open folder.
- Search within the current location.
- Deleting a folder keeps its tracks. Organizing never moves or duplicates audio files. Folders have a single level.
Playback and notesImproved
- Continuous playback between tracks, with previous and next.
- Playback controls keep working on the lock screen.
- Playback follows the order of the library or the folder you started from.
- Persistent manual order for the library.
- A player inside the notes screen; sort notes by position in the song or by creation date.
- Smoother playback while you read or edit lyrics.
ExportPro
- Analysis as JSON.
- Artwork as JPEG or PNG.
- Audio copy with artwork, with lyrics, or with both.
- Exported lyrics keep what you saved: plain text, or line-synced timings.
- The JSON contains no lyrics, timings or notes. Notes stay in TrackScope.
Audio copies are exported one at a time through the system share sheet. The original stays intact and the audio is not re-encoded. Supported: compatible variants of MP3, M4A, FLAC, WAV and AIFF/AIF — availability depends on the format and variant of each file. There is no standalone TXT/LRC export and no direct delivery to music distributors.

FAQ
Questions about TrackScope.
