# Crop vs Modbus TCP Tools

The clearest difference is iOS requirement: Modbus TCP Tools at 15.1 against Crop's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Crop sells 1 one-off in-app purchase and Modbus TCP Tools sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
