# IEEE Volta vs Circuit Challenge

The clearest difference is iOS requirement: IEEE Volta at 8.0 against Circuit Challenge's 13.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
