# SMS Plus vs Sound meter

The clearest difference is iOS requirement: SMS Plus at 7.0 against Sound meter's 12.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SMS Plus sells 1 one-off in-app purchase and Sound meter sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
