# 司空 vs 招标管家

The clearest difference is update cadence: 司空 at every 3 weeks against 招标管家's every 2 months. 招标管家's advantage is iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 司空 sells 4 one-off in-app purchases and 招标管家 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

司空 ships an update every 3 weeks, 招标管家 every 2 months. The most recent releases landed on October 18, 2026 and October 27, 2026 respectively.
