Verdict

The call

The clearest difference is ads: Modal Math at none against Duolingo's shown. Modal Math also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.0). Duolingo's advantage is update cadence (weekly vs every 5 weeks) and ratings volume (5.5M vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.
