# Transformer Calculation Tool vs Electrical Systems Pro Suite

The clearest difference is iOS requirement: Transformer Calculation Tool at 13.0 against Electrical Systems Pro Suite's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Transformer Calculation Tool sells 1 one-off in-app purchase and Electrical Systems Pro Suite sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
