# 仪器信息网 vs 水泥网APP

The clearest difference is iOS requirement: 仪器信息网 at 13.0 against 水泥网APP's 15.1. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 仪器信息网 sells 10 one-off in-app purchases and 水泥网APP sells 18 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on August 31, 2026 and September 10, 2026 respectively.
