Built for founders, writers, and developers who need long, uninterrupted sprints. Set 30, 60, or 90-minute deep work sessions with a 10-minute audio reminder and end alarm.
Three steps to a productive deep work session.
Select 30, 60, or 90 minutes — or type any custom duration. Research shows 90-minute cycles match natural ultradian rhythms for peak focus.
Press Start, close all distractions, and work. A subtle chime plays every 10 minutes to keep you anchored in time without breaking your flow.
When your sprint ends, a clear alarm fires. Step away for 10–20 minutes before your next session. Consistent rest is what makes deep work sustainable.
Deep Work is a term coined by productivity researcher Cal Newport, defined as cognitively demanding tasks performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skills, and are hard to replicate. Contrast this with “Shallow Work” — non-cognitively demanding tasks (emails, meetings, admin) that can be performed while distracted.
Extended focus sessions (60–90 minutes) outperform the classic 25-minute Pomodoro for complex cognitive tasks because they allow your brain to fully enter a state of flow. It typically takes 15–20 minutes for the prefrontal cortex to engage deeply with a challenging problem. Interrupting at 25 minutes cuts the session before peak cognitive performance is reached.
A focus timer helps you block out specific periods of uninterrupted time for "deep work." By committing to a set duration, like 60 minutes, you train your brain to ignore distractions and achieve flow state.
Research suggests that humans can maintain peak concentration for about 90 minutes. Beginners should start with 30 or 60-minute sprints, while experienced deep workers can push for the full 90 minutes.
A Pomodoro timer breaks work into short, 25-minute intervals with frequent 5-minute breaks. A Focus timer is designed for longer, sustained periods of deep work (30 to 90 minutes) without interruptions.
