Ways to Use Forty-Five Minutes
- The 45/15 rhythm — work for 45 minutes, rest for 15. It's a popular alternative to 25/5 for people who need more time to get into a task.
- Exam section practice — time yourself on a paper section to build pacing before the real thing. See our exam timers for silent desk options.
- Classes and meetings — keep a lesson, workshop or meeting to time with a countdown everyone can see.
- Workouts — a 45 minute session covers a full gym routine or a long run.
- Homework for older students — one subject, one block, then a real break.
Longer or Shorter?
If 45 minutes is a stretch, try the 30 minute timer. For a full hour of deep work, use the 1 hour timer.
Screen-Free Focus
A flip-to-start pomodoro timer cube with a 50-minute face, or a silent visual timer, lets you run long focus blocks with your phone out of reach.
45 Minute Timer — FAQ
Does the timer keep running if I switch tabs?
Yes. The countdown is based on the clock, not the tab, so it stays accurate in the background and the alarm is scheduled to sound on time. The time left also shows in the browser tab title.
What is the 45/15 method?
It's a work rhythm of 45 minutes of focused work followed by a 15-minute break — a longer alternative to the classic 25/5 Pomodoro.
