Verdict

The call

The clearest difference is rating: Kango at 4.2 against CoTutor's 2.0. Kango also leads on update cadence (every 2 days vs every 2 weeks) and ratings volume (5 vs 1). CoTutor's advantage is ads (none vs shown) and iOS requirement (15.1 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
