Verdict
The clearest difference is in-app purchases: Deen at none against 66 Challenge's 3. Deen also leads on ratings volume (1.9K vs 5). 66 Challenge's advantage is update cadence (every 5 days vs every 3 weeks) and iOS requirement (13.0 vs 15.6). On price, rating, ads and device support there is nothing between them.
