# Mobile Authenticator vs AI PDF Translate

The clearest difference is iOS requirement: AI PDF Translate at 15.1 against Mobile Authenticator's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Mobile Authenticator sells 2 in-app purchases, starting at $7.99 per 7 days and AI PDF Translate sells 4 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
