Verdict

The call

The clearest difference is rating: edX online learning at 4.8 against Octo's 3.0. edX online learning also leads on review sentiment (82% vs 50%) and ratings volume (11K vs 2). Octo's advantage is update cadence (weekly vs every 5 weeks) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.
