# Pan vs Kayris

The clearest difference is rating: Kayris at 5.0 against Pan's 4.2. Kayris also leads on iOS requirement (17.5 vs 26.0). Pan's advantage is ratings volume (10 vs 1) and update cadence (fortnightly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
