Black Focus

什么是 Black Focus？

Black Focus does one thing: helps you focus. Count down to a goal or count up freely - your session, your rules. A pitch-black fullscreen timer that lives on your lock screen and runs in the background without interruption. Build daily streaks, track your stats, tag your sessions, and share your progress publicly at blackfocus.app/stats/you. No clutter. No paywalls. Optional Do Not Disturb. Just you and the clock.
