1 Hour Timer
A free, full-screen 1 Hour countdown with an alarm. Press Start and it counts down from 1 Hour; when it reaches zero, the alarm sounds.
How it works
One hour covers a full deep-work block, a timed practice exam, and a common checkpoint interval for slow-cooking. An hour is long enough to get through a substantial chunk of complex work in one sitting, and it's the standard section length for many standardized practice tests, which makes it a useful length to rehearse working under.
For deep work, close everything unrelated to the task before starting the timer — the point of a full hour is an uninterrupted stretch, and the first several minutes of any deep-work block go toward regaining focus after a distraction, so even one check-in costs more than the minute it takes.
Common uses
- Running a full 60-minute deep-work block on one task with no interruptions.
- Practicing under real exam conditions with a 1-hour time limit.
- Checking a slow-cooked or braised dish at hourly intervals.
Frequently asked questions
- Does the 1 Hour timer keep running if I switch tabs?
- Yes. The 1 Hour countdown is based on the real clock, so it stays accurate in the background and the alarm still rings when time is up.
- Will it make a sound when the time is up?
- Yes — a short alarm beep plays when the countdown reaches zero. Make sure your device isn't muted.
- How long does it take to get into deep focus?
- Many people report it takes roughly 15-20 minutes of uninterrupted work to reach full focus after starting or after an interruption. That's a large share of a 1-hour block, which is why protecting the full hour from check-ins matters more than the total time spent.
- Why do practice exams use 1-hour sections?
- An hour mirrors the section length of many standardized tests, so practicing with the same time limit trains pacing, not just content knowledge. Timing practice sessions the same way as the real exam is a commonly recommended way to build accurate pacing habits before test day.
