# Delta vs Ed3D

The clearest difference is device support: Delta at 4 against Ed3D's 2. On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Delta sells 3 one-off in-app purchases and Ed3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
