# OpenFile vs OneOpen

The clearest difference is iOS requirement: OneOpen at 17.0 against OpenFile's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. OpenFile sells 2 in-app purchases, starting at $2.99 per month and OneOpen sells 2 in-app purchases, starting at $0.99 per year. Whichever you choose, the download price is not the number that matters.
