# PDF转换器 vs 文心

The clearest difference is update cadence: 文心 at every 2 weeks against PDF转换器's monthly. PDF转换器's advantage is iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF转换器 sells 3 in-app purchases, starting at $1.49 per month and 文心 sells 19 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PDF转换器 ships an update monthly, 文心 every 2 weeks. The most recent releases landed on September 16, 2026 and September 26, 2026 respectively.
