# JavaScript Coding vs Diff Checker

The clearest difference is device support: JavaScript Coding at 3 against Diff Checker's 1. JavaScript Coding 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. JavaScript Coding sells 2 in-app purchases, starting at $2.99 per year and Diff Checker sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
