# 字加 vs 石头阅读

The clearest difference is rating: 石头阅读 at 4.5 against 字加's 3.0. 石头阅读 also leads on ratings volume (164 vs 5) and update cadence (every 2 weeks vs every 2 months). 字加's advantage is ads (none vs shown) and review sentiment (100% vs 67%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

石头阅读 holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: 石头阅读 has 164 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of 字加's written reviews are positive against 67% of 石头阅读's, so the app with the better star average is not the one people write more warmly about.

字加 ships an update every 2 months, 石头阅读 every 2 weeks. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
