# o46scope vs VoltKit

The clearest difference is device support: o46scope at 3 against VoltKit's 1. o46scope also leads on iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.

Both are free to download. o46scope sells 1 in-app purchase, starting at $19.99 per year and VoltKit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
