ReceptionRating · Positive reviews · Number of ratings

udn 讀書館 holds the better App Store score, 2.5 against 1.0.

Written reviews complicate that: 53% of Readmoo 分享書's written reviews are positive against 50% of udn 讀書館's, so the app with the better star average is not the one people write more warmly about.

Readmoo 分享書 ships an update every 3 months, udn 讀書館 every 6 weeks. The most recent releases landed on August 12, 2026 and September 19, 2026 respectively.
