Focus Timer
A distraction-free timer for deep work. Choose a preset or set a custom duration. Get notified when your session ends. Track your daily focus sessions — all data stays on your device.
Why Use a Focus Timer
Research consistently shows that focused, uninterrupted work sessions produce dramatically better results than constant multitasking. A focus timer creates structure by committing you to a specific block of time, eliminating the temptation to check email or social media. The timer serves as a commitment device that makes deep work easier to start and sustain. Session tracking lets you see how many focused blocks you complete each day, building awareness of your productive patterns.
Choosing the Right Duration
The best timer duration depends on your task and energy level. Twenty-five minutes works well for getting started or when motivation is low, following the classic Pomodoro approach. Forty-five minutes suits writing, studying, or moderately complex tasks that need sustained attention. Sixty minutes is ideal for deep work sessions like programming, research, or creative projects. Set any custom duration up to 180 minutes for extended focus blocks. Start with shorter sessions and gradually increase as your focus stamina builds over days and weeks.
The Science of Focused Work
Human attention follows ultradian rhythms of approximately 90 minutes of peak focus followed by 20 minutes of lower alertness. Most people can sustain 2 to 4 hours of peak cognitive work per day. Sound alerts and browser notifications ensure you know when a session ends even if you are in another tab. All session data is saved locally in your browser, so your focus history stays private and persists across visits without any account or server connection.
