# 小读书 vs Common Reader

The clearest difference is rating: Common Reader at 5.0 against 小读书's 1.0. Common Reader also leads on update cadence (every 2 days vs every 8 days). 小读书's advantage is review sentiment (100% vs 75%) and monetization model (free vs free with in-app purchases). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Common Reader holds the better App Store score, 5.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 100% of 小读书's written reviews are positive against 75% of Common Reader's, so the app with the better star average is not the one people write more warmly about.

小读书 ships an update every 8 days, Common Reader every 2 days. The most recent releases landed on September 22, 2026 and October 14, 2026 respectively.
