# RoomPipe vs 管道计算器Pro

The clearest difference is iOS requirement: 管道计算器Pro at 13.0 against RoomPipe's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. RoomPipe sells 1 one-off in-app purchase and 管道计算器Pro sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
