# Flow Free vs Mail Sort

The clearest difference is iOS requirement: Flow Free at 13.0 against Mail Sort's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Flow Free sells 10 one-off in-app purchases and Mail Sort sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
