Stackwax
Read full descriptionHide full description
Stackwax is the shelf for DJs. You hear a track. You need the BPM, the key, the Camelot code. You need it in your library before the night is over. You want to buy it on vinyl. StackWax does all of it in one tap. Hold your phone up. StackWax identifies the track, detects the BPM and key in real time, gives you the Camelot code, and shelves it directly into your library. Then the library works for you. Sort by BPM, by key, by Camelot. Drag tracks into playing order and sketch your next set before you step behind the decks. When you find something you want on vinyl, tap through to the Discogs listing and buy it without leaving the app. Connect your existing Discogs collection and import your records. Everything in one place, organised the way DJs think. Built for DJs who take music seriously. Works in clubs, record shops, at home, anywhere music is playing. Free to start. No credit card required.

AI DJ Studio
Read full descriptionHide full description
Split any song into layers, then mix with them. Bring a track from Files and AI DJ Studio separates it into vocal, drums, bass and melody, each on its own pad. Tap one to drop it out. Hold it to hear it alone. Both decks run under a single playhead, so the beat grid, the loops and the scratch move the whole song, not a fragment. MARK IT AT HOME, HIT IT IN THE SET The cue point of a club deck needs a headphone feed a phone does not have. So you prepare instead: listen at home, drop a mark where the drop is, name it in your own words. In a set the mark is a button. Press it and the track starts exactly there, snapped to the beat, with no fade to knock it out of time. MIX WITH ONE SPEAKER Line up the beat markers on the two waveforms, or press SYNC. The MIX button takes the whole transition on its own: it matches tempo, enters at your mark, and crossfades over eight bars. A MASHUP IN ONE PRESS The vocal of one deck over the instrumental of the other. Six faders move at once, on tracks written to fit each other: every factory pair shares a tempo and a compatible key. PRESS YOUR OWN RECORDS Describe a track and it arrives whole, one to three minutes, at the tempo and key you asked for, with cover art on the label and already split into layers. ALSO INSIDE Three band EQ with true kill, a bipolar filter, seven momentary effects locked to the beat, loops from one to sixteen bars, a nine pad kit of sampled percussion, and a landscape console with two full size platters. Curated tracks open by watching a short video. Credits pay for AI generation. Premium removes ads and separates as much as you want. Premium is an auto-renewable monthly subscription.

Verdict
The clearest difference is ads: Stackwax at none against AI DJ Studio's shown. Stackwax also leads on update cadence (every 5 days vs fortnightly) and iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
