# FocusTime vs Koza

The clearest difference is ads: Koza at none against FocusTime's shown. Koza also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). 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.
