# EqCalc vs Materials Lab

The clearest difference is device support: Materials Lab at 4 against EqCalc's 2. Materials Lab also leads on iOS requirement (15.0 vs 18.2). On price, ads and in-app purchases there is nothing between them.

Both are free to download. EqCalc sells 1 one-off in-app purchase and Materials Lab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
