# Critical vs Night Shift

The clearest difference is ads: Night Shift at none against Critical's shown. Critical's advantage is iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Critical sells 10 one-off in-app purchases and Night Shift sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
