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.

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.

Verdict
The clearest difference is update cadence: Stackwax at every 5 days against GruKit's every 2 months. Stackwax also leads on iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
