Online Timers
Start with the timing tool that fits the job: count down to a deadline, measure elapsed time, or run repeating work and rest intervals.
Countdown Timer
Set a countdown for cooking, work sessions, exams, events, breaks, or any task that needs an alarm at the end.
Online Stopwatch
Measure elapsed time with lap tracking and millisecond precision directly in your browser.
Interval Timer
Build repeating work and rest rounds for HIIT, Tabata, stretching, cardio, and circuit training.
Choose the Right Timer
Use the countdown timer when you already know how long something should take and need a clear finish alert. It is the best fit for study blocks, cooking, meetings, presentations, and timed breaks.
Use the online stopwatch when you need to measure how long something actually takes. Laps help compare repeated attempts, split stages, or track progress without resetting the whole timer.
Use the interval timer when the schedule repeats. Workouts, Pomodoro-style focus sessions, drills, and recurring rest periods are easier to manage when the timer automatically moves from one round to the next.
Useful Timer Setups
Focused work: start with 25 minutes of work and 5 minutes of rest. If the task needs deeper concentration, try 45 minutes of work and a 10-minute break.
Meetings: use a visible countdown for agenda items. A 10-minute countdown for each topic keeps the group aware of time without interrupting the discussion.
Fitness: use the interval timer for repeated work/rest rounds, and the stopwatch when you need to record split times or personal bests.
Cooking and routines: use the countdown timer when the end moment matters more than measuring elapsed time.
Timer Accuracy Notes
These tools run in your browser and use your device clock. Browser tabs can be throttled when they are hidden or when a device is under heavy load, so keep the page visible for the most reliable visual updates. For critical timing, use a dedicated timing device as a backup.
