Verdict

The call

The clearest difference is ads: Cognify at none against Polym's shown. Cognify also leads on review sentiment (100% vs 70%) and rating (5.0 vs 4.6). Polym's advantage is update cadence (every 11 days vs monthly) and ratings volume (36 vs 5). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.
