The coach after the set
Your set,
graded.
Drop in a recorded DJ set. MixGrade analyzes every transition on-device (beatmatching, key clashes, energy flow, levels) and hands you a MixScore out of 100 in about a minute.

How it works
Sixty minutes of mixing, sixty seconds of truth.
Drop your set
Import any recording from Files, your controller app or a voice memo. MP3, M4A, WAV, AIFF, FLAC. Up to three hours.
On-device analysis
Real DSP scans every beat: tempo curves, chromagrams, loudness, transition zones. No upload, no server, no waiting room.
Get your grade
A MixScore out of 100 with five sub-scores and per-transition feedback. Know exactly which blend dragged, and why.
What gets measured
Eight readouts. One number.
Beatmatching drift
Tempo instability inside every transition zone, measured to the BPM decimal. Hear-it-clash detection included.
Key clashes (Camelot)
Harmonic compatibility of every blend: 8A into 9A passes, 8A into 3B gets flagged with the dissonance to prove it.
Energy flow
Does the set actually build? Peak placement, sag and dead air mapped across the full runtime.
Levels & clipping
EBU R128 loudness plus true-peak scans. “You recorded in the red at 12:40”, down to the second.
Auto-tracklist
Shazam identifies your tracks and boundaries. Export the tracklist as text or 1001tracklists format.
AI coach
On-device Apple Intelligence turns the raw metrics into a few paragraphs of plain-language coaching.
Share card
Your score as a 1080×1920 card: grade, energy silhouette, key journey. Built to be the “rate my mix” post.
Progress over time
Every analysis saved on-device. Watch beatmatching climb +12 month over month.
Why DJs trust it
No subscription.
€9.99 once. Three full analyses free, then Pro forever. Nobody needs another monthly bill to find out their blend at 41:32 was muddy.
Your audio never leaves your iPhone.
The whole pipeline runs on-device. No accounts, no cloud, no analytics. Your unreleased edits stay unreleased.
Built on real DSP, not vibes.
FFTs, chromagrams, EBU R128 loudness: published methods with documented thresholds. Not a wrapper around someone else’s API.
FAQ
Before you ask
Is it a subscription?+
No. MixGrade is €9.99 once, yours forever. You get three full analyses free first, so you can judge the product before paying a cent.
Does my mix get uploaded?+
No. The entire analysis pipeline runs on your iPhone using Apple’s Accelerate framework. If you enable track identification, only compact audio fingerprints go to Apple’s Shazam service, never your recording.
Does it work with unreleased tracks?+
Analysis, yes: beatmatching, keys, energy and levels are computed from the audio itself. Track identification needs a Shazam catalog match, so unreleased material shows up as “Unknown Track” with correct boundaries.
What formats are supported?+
MP3, M4A, WAV, AIFF and FLAC. Sets up to three hours, imported from Files, AirDrop or the share sheet.
