# Ground School vs Sky

The clearest difference is iOS requirement: Ground School at 16.0 against Sky's 18.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Ground School sells 11 in-app purchases, starting at $49.99 per month and Sky sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
