Verdict
The clearest difference is in-app purchases: e at none against 书中课堂's 8. e also leads on ratings volume (7 vs 1). 书中课堂's advantage is update cadence (monthly vs every 70 months) and device support. On price and rating there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 书中课堂 sells 8 one-off in-app purchases. e asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for e against 5.0 for 书中课堂. That said, the two scores are not equally well evidenced: e has 7 ratings behind it against 1, so its average is the more settled of the two.
e ships an update every 70 months, 书中课堂 monthly. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
