# Ed3D vs CastReader

The clearest difference is iOS requirement: Ed3D at 13.4 against CastReader's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Ed3D sells 1 one-off in-app purchase and CastReader sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
