Free Online Count Up Timer
Our count up timer measures how long something takes. It starts
from zero and runs until you stop it. It is pre-set to count from 0:00 to 10 minutes. Set any stop time you need, or set the stop time to 99 hours with 99h and manually stop the timer when the event is done.
A count up timer tells you how much time you've used. This is good for meetings that run variable lengths, activities you want to time, tasks to benchmark, or an event where the end point is unknown.
What to Use a Count Up Timer For
Count up timers suit situations where the duration is unknown, open-ended, or needs to be recorded:
- Meetings and calls — See how long a meeting has run. A count up display on a shared screen is an honest signal of time used.
- Task benchmarking — How long does it actually take to complete a specific task? Start the timer, do the work, stop it when done. Repeat over several sessions to get a reliable baseline.
- Athletic and fitness events — Time a run, a swim, a cycling interval, or a set. For timing any athletic events.
- Speeches and presentations — Monitor how long a speaker has been talking without imposing a hard limit. Good for practice sessions where the goal is to find the length of a talk rather than hit a fixed target.
- Laboratory and research timing — Elapsed time measurement for experiments, observations, or procedures where the duration needs to be recorded.
- Customer service and response times — Time how long a customer interaction, support call, or service task takes. Good for training, benchmarking, identifying bottlenecks.
- Kids and games — How fast can you solve the puzzle, finish the course, or complete the challenge? A count up timer turns an activity into a personal best competition.
- Open-ended work sessions — Start the timer when you begin a task and stop it when you're done. Over time, elapsed time records tell you where your hours actually go.
Time Display Formats
The Count Up Timer defaults to 0:00 format, which grows as time accumulates. We support eight display formats for different use cases:
-
0— Single digit minimum, expanding as needed. Displays5at 5 seconds,10at 10 seconds,1:00at one minute. The most compact format — used by the standard timer as its default. -
00— Two digit minimum. Shows at least two digits, expanding at 60 seconds and again at one hour. 0:00— Minutes and seconds minimum, single digit hours. The Count Up Timer default. Clean and readable for most elapsed time use cases.00:00— Minutes and seconds minimum, two digit hours. Nice when you want a consistent display width without distracting shifts.-
0:00:00— Hours, minutes, and seconds minimum, single digit hours. Good for long sessions where an hour could be reached. 00:00:00— Hours, minutes, and seconds minimum, two digit hours. Maximum width for long-running displays, but forces time display to shrink to fit.0 secs only— Display time only in seconds. Three minutes shows as180. Good for athletic timing, scientific measurement, or when total seconds is meaningful.00:00 mins &secs only— Displays minutes and seconds only, stripping hours entirely. One hour thirty minutes thirty seconds shows as90:30. Good for production timing, coaching, or when seeing total minutes and seconds is better.
Count Up Timer — Common Questions
Does this timer work on phones and tablets?
Yes. The Count Up Timer works on any modern browser across desktop, mobile, and tablet. The display scales to fit your screen size.
Will the alarm sound if I switch to another tab?
Yes. Whether you minimize the browser window or place the timer on another tab, alarms should sound.
Can I set an alarm at a specific elapsed time?
Yes. Set the stop time in the action bar to the time at which you want the alarm to sound. For example use 00:45:00 for 45 minutes. Timer counts up
and the alarm sounds when it reaches that time. Set stop time to 99h to have timer run with no alarm for up to 99 hours.
Can I switch between count up and countdown?
Yes. Click the swap button between the start and stop time fields in the action bar to reverse the two values. If the start time is lower than the stop time the timer counts up;if start time is higher it counts down.
Does pausing the timer lose time?
No. Pausing preserves the elapsed time. When you press Start again the count up resumes from where it stopped. Good when the total time elapsed is being measured.
How do I share my timer setup with my team?
Configure the timer's start time, stop time, alarm, display format, and title, then click the icon under the time display and copy the URL shown. Anyone who opens that link loads your count up timer as you set it up.
