Verdict
The clearest difference is ads: Ozzy Nautilus at none against Ryzon's shown. Ozzy Nautilus also leads on monetization model (free vs free with in-app purchases) and rating (4.8 vs 4.5). Ryzon's advantage is update cadence (every 3 weeks vs every 6 months) and ratings volume (36 vs 5). On price, in-app purchases, device support and iOS requirement there is nothing between them.
