Verdict

The call

The clearest difference is update cadence: Polymath at every 3 days against EPS TOPIK's every 5 weeks. Polymath also leads on rating (5.0 vs 4.7). EPS TOPIK's advantage is ratings volume (31 vs 1) and iOS requirement (15.0 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.
