TrackScope: Music Analyzer

Import a track and see what is inside it. TrackScope reads a song on your iPhone and shows its key, tempo, structure, energy, instruments and loudness, without opening a DAW and without sending your audio anywhere.

WHAT IT READS
• Key, and where it changes through the track
• Tempo in BPM, with beats and bars
• Structure: sections, segments and phrases
• Energy across the track
• Which instruments are playing, and when
• Loudness: integrated, short-term and peak

WHILE IT PLAYS
Play the track and the timeline follows it: the section you are hearing, the key at that moment, the instruments in it.

IT STAYS ON YOUR DEVICE
The analysis runs on your iPhone. Your audio is not uploaded and there is no account to create. Optional lyric timing suggestions may require an initial download of an Apple language model; audio and lyrics are processed on-device.

TAKE THE RESULT WITH YOU
Export any analysis as a JSON file and share it wherever you work. Lyrics, timing marks and notes stay inside the app.

YOUR LYRICS AND NOTES
With Pro, paste and edit lyrics and save notes with optional playback times. Mark lyric lines while listening, or use local timing suggestions where available and complete or correct them by tapping lines. Suggestions may be incomplete; accurate automatic synchronization is not guaranteed. Read saved text even when the audio file is unavailable.

FREE AND PRO
Free includes three welcome analyses, then one per calendar week with no rollover, and a library of three tracks. Pro includes unlimited analyses and library, JSON export, and creating or editing lyrics and notes. If Pro ends, you can still read and delete saved lyrics and notes.

TrackScope tells you what its analysis finds. It is a fast read of a track, not a measuring instrument.
