# edX online learning vs Octo

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.

Both are free to download. edX online learning sells 9 one-off in-app purchases and Octo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

edX online learning holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: edX online learning has 11K ratings behind it against 2, so its average is the more settled of the two.
