# ChronoDNA vs CaseBack

The clearest difference is device support: ChronoDNA at 3 against CaseBack's 1. ChronoDNA also leads on iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. ChronoDNA sells 3 in-app purchases, starting at $9.99 per month and CaseBack sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
