# Highlight PDF vs SecurePass AI

The clearest difference is iOS requirement: SecurePass AI at 13.0 against Highlight PDF's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Highlight PDF sells 3 in-app purchases, starting at $7.99 per month and SecurePass AI sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
