# Grammar vs Ed3D

The clearest difference is iOS requirement: Ed3D at 13.4 against Grammar's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Grammar sells 1 one-off in-app purchase and Ed3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
