# Volt vs TreadTap

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

Both are free to download. Volt sells 1 in-app purchase, starting at $6.99 per year and TreadTap sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
