Verdict

The call

The clearest difference is rating: WORM.dance at 4.9 against Ballet Class's 3.8. WORM.dance also leads on review sentiment (100% vs 68%) and update cadence (fortnightly vs every 3 months). Ballet Class's advantage is ratings volume (77 vs 14) and iOS requirement (12.0 vs 14.0). On price, ads, in-app purchases and monetization model there is nothing between them.
