About Stopwatch Online
The most advanced free timing suite online, featuring Stopwatch, Countdown, and Tabata interval training with background timing, live updates, and audio feedback for athletes and professionals.
Our Mission
We created the best stopwatch online to provide athletes, coaches, fitness enthusiasts, and professionals with a comprehensive timing suite. Our free platform combines three powerful timer types - Stopwatch for lap timing, Countdown for time-based challenges, and Tabata for high-intensity interval training - all with background timing technology that keeps your timers running even when you navigate away.
Whether you're doing HIIT workouts, timing sprint intervals, tracking study sessions, or managing presentations, our stopwatch online tool provides the accuracy and functionality you need. Live tab updates show real-time values at 60 frames per second, while audio cues and mobile vibration keep you focused on your activity without constantly checking the screen.
