# Materials Lab vs cella

The clearest difference is device support: Materials Lab at 4 against cella's 2. Materials Lab also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

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