# Codecademy Go vs UpperMark eReader

The clearest difference is review sentiment: UpperMark eReader at 100% against Codecademy Go's 52%. UpperMark eReader also leads on in-app purchases (none vs 4) and update cadence (every 2 weeks vs every 6 weeks). Codecademy Go's advantage is rating (4.8 vs 4.0) and ratings volume (38K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Codecademy Go sells 4 in-app purchases, starting at $29.99 per month. UpperMark eReader asks for nothing beyond the download.

Codecademy Go holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Codecademy Go has 38K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 52% of Codecademy Go's written reviews are positive against 100% of UpperMark eReader's, so the app with the better star average is not the one people write more warmly about.

Codecademy Go ships an update every 6 weeks, UpperMark eReader every 2 weeks. The most recent releases landed on October 20, 2026 and October 9, 2026 respectively.
