Our stopwatch goes beyond basic timing with these powerful features:
Record intermediate times while the stopwatch continues running. Perfect for tracking segments of a race or workout.
Measure elapsed time at specific points while the timer continues. Great for comparing performance across intervals.
Set a specific time to count down from, with visual and audio alerts when time expires.
View all your recorded lap and split times in an organized list for easy analysis.
Our stopwatch is versatile enough for many timing needs:
Use the Lap function for interval training to track each segment separately while maintaining the overall time. Use Split timing to compare your current pace against previous segments.
Lap timing records the time at the moment you press the button, then continues timing from that point. Each lap time shows the duration of that specific segment.
Split timing records the elapsed time at specific points while the overall timer continues running. Each split shows the total time elapsed up to that point.
Use Lap timing when you want to measure individual segments independently. Use Split timing when you want to compare your current progress against earlier checkpoints in the same activity.
