Verdict
The clearest difference is rating: Cengage Read at 4.2 against Octo's 3.0. Cengage Read also leads on in-app purchases (none vs 1) and ratings volume (4.2K vs 2). Octo's advantage is review sentiment (50% vs 20%) and update cadence (weekly vs every 2 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Octo sells 1 one-off in-app purchase. Cengage Read asks for nothing beyond the download.
Cengage Read holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Cengage Read has 4.2K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of Octo's written reviews are positive against 20% of Cengage Read's, so the app with the better star average is not the one people write more warmly about.
Octo ships an update weekly, Cengage Read every 2 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
