# FocusU vs ONE

The clearest difference is ads: FocusU at none against ONE's shown. ONE's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.5). On price 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.
