What Is a Focus Timer?
A focus timer is a countdown you set before starting a single task, so you work with full attention until it rings and then take a planned break. Giving work a clear start and end makes it easier to begin, stops you from drifting into other tabs, and builds in rest before you get tired. The best length depends on the task: 25 minutes to get going, 52 or 90 minutes for deep work.
Deep work
Block 52 or 90 minutes for your most important task before email.
Studying
25 minute blocks with breaks keep you fresh through long sessions.
Working from home
A visible countdown gives your day the structure an office would.
ADHD
Short, visible blocks help with time blindness. See the ADHD timer for 10/2 and 15/5.

How to Use This Timer
- Pick a preset: 25/5, 52/17 or 90/20.
- Write down the one task for this block and press Start.
- Work until the alarm rings, then press Start break and step away.
- Repeat, and take a longer break after about two hours.
💡 One task per block
Decide what you'll work on before pressing Start, and close everything else. A focus timer only works if the block has a single job. If you keep getting cut off in the middle of good work, try a count-up Flowtime timer instead.
Frequently Asked Questions
What is a focus timer?
A countdown you set for one task, so you work with full attention until it rings and then take a planned break.

25 minutes is a good default. Once that feels easy, try 50–52 minutes, and up to 90 minutes for deep creative work. Always follow a session with a break.
What is the best focus timer technique?
