# Ostello vs Data & AI Hub

The clearest difference is iOS requirement: Data & AI Hub at 15.1 against Ostello's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Ostello sells 5 one-off in-app purchases and Data & AI Hub sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
