Verdict

The call

The clearest difference is ads: edX online learning at none against RecallKit's shown. edX online learning also leads on ratings volume (11K vs 1) and iOS requirement (15.0 vs 17.6). RecallKit's advantage is update cadence (every 2 weeks vs every 5 weeks) and rating (5.0 vs 4.8). On price, in-app purchases, monetization model and device support there is nothing between them.
