# 当当云阅读 vs 西西弗

The clearest difference is rating: 当当云阅读 at 4.7 against 西西弗's 4.1. 当当云阅读 also leads on ratings volume (985 vs 10) and update cadence (every 2 weeks vs monthly). 西西弗's advantage is in-app purchases (none vs 21) and review sentiment (96% vs 74%). On price, ads and device support there is nothing between them.

Both are free to download. 当当云阅读 sells 21 in-app purchases, starting at $2.49 per month. 西西弗 asks for nothing beyond the download.

当当云阅读 holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: 当当云阅读 has 985 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 74% of 当当云阅读's written reviews are positive against 96% of 西西弗's, so the app with the better star average is not the one people write more warmly about.

当当云阅读 ships an update every 2 weeks, 西西弗 monthly. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
