# 网格交易工具箱 vs 計算工坊

The clearest difference is device support: 計算工坊 at 3 against 网格交易工具箱's 1. 計算工坊 also leads on iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 网格交易工具箱 sells 4 in-app purchases, starting at $0.99 per month and 計算工坊 sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
