# StressTable2021 vs Welding Reference Pro

The clearest difference is device support: StressTable2021 at 4 against Welding Reference Pro's 1. StressTable2021 also leads on iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. StressTable2021 sells 1 one-off in-app purchase and Welding Reference Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
