# 集云 vs ReflowPDF

The clearest difference is update cadence: ReflowPDF at fortnightly against 集云's every 2 months. 集云's advantage is review sentiment (75% vs 67%) and iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 集云 sells 3 in-app purchases, starting at $0.99 per month and ReflowPDF sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

集云 ships an update every 2 months, ReflowPDF fortnightly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
