# 文心 vs CAJ转换器

The clearest difference is update cadence: 文心 at fortnightly against CAJ转换器's every 2 months. 文心 also leads on review sentiment (33% vs 20%). CAJ转换器's advantage is iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 文心 sells 19 in-app purchases, starting at $0.99 per month and CAJ转换器 sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

文心 ships an update fortnightly, CAJ转换器 every 2 months. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
