# PrincipleX vs OnceDone

The clearest difference is device support: OnceDone at 3 against PrincipleX's 1. OnceDone 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. PrincipleX sells 5 in-app purchases, starting at $2.99 per month and OnceDone sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
