# Task One vs ONE

The clearest difference is device support: ONE at 3 against Task One's 1. ONE also leads on iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
