# USB Challenge vs Sequence Cubes

The clearest difference is iOS requirement: USB Challenge at 7.1 against Sequence Cubes's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

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