Verdict

The call

The clearest difference is in-app purchases: CourseCat at none against Polish by Nemo's 1. CourseCat also leads on rating (5.0 vs 4.8) and update cadence (fortnightly vs every 6 weeks). Polish by Nemo's advantage is ratings volume (2K vs 1) and device support (3 vs 1). On price and ads there is nothing between them.
