Verdict
The clearest difference is rating: LOOPBAR at 5.0 against S's 2.6. LOOPBAR also leads on update cadence (every 3 weeks vs every 7 months) and price ($0.99 vs $2.99). S's advantage is ratings volume (11 vs 1) and iOS requirement (15.6 vs 18.5). On ads, in-app purchases, monetization model and device support there is nothing between them.
