Focus timer for deep work and study

How to use it

Long focus, done well

45 minutes of focus and a 5 minute break, repeating until you finish. No account needed.

When to use longer sessions

Some work needs time to warm up: writing, coding, design, studying for an exam, or any problem you have to hold in your head. A 25 minute round can end just as you get going. Deep focus gives you 45 minutes by default, and you can stretch each block up to 90.

45 or 90 minutes?

  • 45 minutes fits most study and work. It's long enough to get deep and leaves room for a short reset.
  • 90 minutes suits big pieces of work when you're rested. Take a longer break afterwards.
  • Not sure? Start with 45. If the break keeps cutting you off, add 15 minutes next time.

Using it as a study timer

Before you start, write down what you'll finish in this block, like one chapter or ten practice questions. Put your phone in another room. On each break, stand up, drink water and look away from the screen. After two or three blocks, stop and review what you learned.

Make it yours

Open the timer settings to set focus from 15 to 90 minutes and breaks from 1 to 30 minutes. Add a background sound: forest rain, waterfall, brown noise, storm at sea, fireplace, rapids or a quiet café. Press Complete when you're done; the time you focused is kept.

Want shorter rounds? The Pomodoro timer runs 25 minutes of focus and 5 minute breaks, four times. Open the Pomodoro timer

Questions

Common questions

What is a focus timer?

A timer that protects a block of time for one task. You set how long to focus, work until it ends, then take a short break. This one repeats focus and break until you press Complete.

How is it different from a Pomodoro timer?

A Pomodoro timer uses short 25 minute rounds and stops after four. Deep focus uses longer blocks, 45 minutes by default and up to 90, and keeps going until you decide to stop. Switch between the two at the top of the timer.

Can I set a 90 minute timer?

Yes. Open the timer settings and set focus to 90 minutes. That's the longest block, so even your longest stretch ends with a break.

Does it play background sounds?

You can play a background sound while you work: forest rain, waterfall, brown noise, storm at sea, fireplace, rapids or a quiet café. A soft chime marks the end of each focus and break.

Do I need an account?

No. Your settings and today's focus time are saved in this browser. Create a Karter account when you want daily focus training and your progress on every device.

Beyond the timer

A timer helps you use your focus. Karter trains it.

Karter is an app that trains focus and concentration. Short daily exercises build the skill: breathing to settle your mind, reflection to see where attention drifts, and reaction drills for steady attention. Then this timer puts it to work.
