# Off vs DoU

The clearest difference is iOS requirement: DoU at 15.6 against Off's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Off sells 2 in-app purchases, starting at $4.99 per 7 days and DoU sells 1 in-app purchase, starting at $6.00 per month. Whichever you choose, the download price is not the number that matters.
