# ChatUp vs HotKey OTP

The clearest difference is device support: HotKey OTP at 4 against ChatUp's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. ChatUp sells 3 in-app purchases, starting at $9.99 per 7 days and HotKey OTP sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
