# 翻译狗 vs CAJ云阅读

The clearest difference is rating: CAJ云阅读 at 4.2 against 翻译狗's 3.6. CAJ云阅读 also leads on update cadence (every 6 days vs monthly) and ratings volume (32 vs 7). 翻译狗's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (50% vs 18%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 翻译狗 sells 14 in-app purchases, starting at $6.99 per month and CAJ云阅读 sells 6 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 3.6. Both are backed by a comparable volume of ratings — 7 and 32 respectively. Written reviews complicate that: 50% of 翻译狗's written reviews are positive against 18% of CAJ云阅读's, so the app with the better star average is not the one people write more warmly about.

翻译狗 ships an update monthly, CAJ云阅读 every 6 days. The most recent releases landed on October 8, 2026 and October 17, 2026 respectively.
