# PDF Pro Reader Edit vs 扫描仪

The clearest difference is update cadence: PDF Pro Reader Edit at every 4 weeks against 扫描仪's every 2 months. 扫描仪's advantage is iOS requirement (11.0 vs 16.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Pro Reader Edit sells 1 one-off in-app purchase and 扫描仪 sells 2 in-app purchases, starting at $40.99 per 3 months. Whichever you choose, the download price is not the number that matters.

PDF Pro Reader Edit ships an update every 4 weeks, 扫描仪 every 2 months. Both last shipped on October 8, 2026.
