# SpamSlap vs Prime Time NTP

The clearest difference is iOS requirement: SpamSlap at 18.0 against Prime Time NTP's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SpamSlap sells 1 one-off in-app purchase and Prime Time NTP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
