# 公式大师Pro vs 极速意见箱

The clearest difference is update cadence: 极速意见箱 at every 4 days against 公式大师Pro's every 3 weeks. 极速意见箱 also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 公式大师Pro sells 4 one-off in-app purchases and 极速意见箱 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

公式大师Pro ships an update every 3 weeks, 极速意见箱 every 4 days. The most recent releases landed on October 8, 2026 and October 7, 2026 respectively.
