# Secure Folder vs AI智换

The clearest difference is iOS requirement: AI智换 at 12.0 against Secure Folder's 16.6. On price and in-app purchases there is nothing between them.

Both are free to download. Secure Folder sells 5 in-app purchases, starting at $2.99 per month and AI智换 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
