Two clocks for your own rhythm
When another distraction pulls you away from a task, the work and rest clocks make the current session visible. Switch to Work as you return, watch focused time add up and take the next step toward the task in front of you.
One more step toward your goal
Finish a draft or solve one more problem. Choose a small target, start the Work clock and switch to Rest when you pause. The running work time and percentage help you bring attention back to your task. When you finish, check how much time you spent focusing.
