MixGrade: Rate My DJ Mix

MixGrade is an iPhone app that grades a DJ set you recorded, returning a MixScore from 0 to 100 with a letter grade, five sub-scores, and concrete feedback on every transition — in minutes. Analysis runs 100% on your device, so your audio never leaves your iPhone. The first 3 full analyses are free, then a single one-time purchase unlocks unlimited use, with no subscription. WHAT YOU GET - MixScore 0-100 with a letter grade from S to D - Five sub-scores: Beatmatching, Harmonic, Energy Flow, Levels, Cleanliness - A card for every transition: tempo drift, key move on the Camelot wheel, bass clash heat, blend style - Interactive set timeline: full waveform colored by energy, tap any transition to listen back - Auto tracklist powered by Shazam, exportable as text - Key Journey: your harmonic path drawn on a custom Camelot wheel - AI coach: short, specific feedback generated on your device - A score card built for "rate my mix" posts - Progress tracking: watch each sub-score climb set over set HOW IT WORKS 1. Record your set as usual: controller, mixer, phone, anything that produces an audio file 2. Import it from Files or the share sheet (mp3, m4a, wav, aiff, flac) 3. Watch transitions appear on the timeline while the analysis runs 4. Get your score, read the feedback, fix the weak spots, go again WHAT IT CATCHES - Tempo drift inside transitions, down to the moment a blend slipped - Key clashes between adjacent tracks, mapped on the Camelot wheel - Bass clash: two basslines fighting in the low end during an overlap - Energy problems: dead air, sagging middles, peaks in the wrong place - Recording issues: clipping ("you were in the red at 12:40"), DC offset, harsh distortion WHY DJS USE IT Posting "rate my mix" and waiting days for two vague comments is a slow way to improve. MixGrade gives you the same critique instantly, consistently, and without ego. And when you do post, use the score card: grade, energy arc, and key journey in one image. PRIVACY Analysis runs 100 percent on-device. Your audio is never uploaded. The optional tracklist feature sends a short audio fingerprint to Apple's Shazam service to identify tracks; skip it and nothing leaves the phone at all. No account, no ads, no tracking. PRICING Free: 3 full analyses, every feature included, nothing crippled. Pro: one one-time purchase unlocks unlimited analyses, full history and trends, and tracklist export. No subscription, no recurring charges. Made for bedroom DJs who want to get good fast. Import the set you recorded last night and find out what it scores.
