# CAJ云阅读 vs 古籍阅读器

The clearest difference is rating: CAJ云阅读 at 4.2 against 古籍阅读器's 1.0. CAJ云阅读 also leads on ratings volume (32 vs 1) and review sentiment (18% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CAJ云阅读 sells 6 in-app purchases, starting at $3.99 per month and 古籍阅读器 sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

CAJ云阅读 holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: CAJ云阅读 has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 18% of CAJ云阅读's written reviews are positive against 0% of 古籍阅读器's.

CAJ云阅读 ships an update every 6 days, 古籍阅读器 every 2 weeks. The most recent releases landed on September 24, 2026 and September 8, 2026 respectively.
