# Computer Science Calculations vs Collision Kit

The clearest difference is device support: Computer Science Calculations at 3 against Collision Kit's 1. Computer Science Calculations 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. Computer Science Calculations sells 3 in-app purchases, starting at $0.99 per 3 months and Collision Kit sells 1 in-app purchase, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.
