# Comet vs Use This

The clearest difference is iOS requirement: Comet at 18.0 against Use This's 26.4. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Comet sells 3 in-app purchases, starting at $20.00 per month and Use This sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
