Verdict
The clearest difference is rating: Spur at 5.0 against Stage Proof's 1.0. Spur also leads on ratings volume (21 vs 1) and iOS requirement (15.1 vs 17.0). Stage Proof's advantage is in-app purchases (none vs 3) and update cadence (every 5 days vs monthly). On price, ads, monetization model and device support there is nothing between them.
