# Ki vs Open Hub

The clearest difference is iOS requirement: Open Hub at 16.0 against Ki's 18.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Ki sells 1 one-off in-app purchase and Open Hub sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
