Free Online Stopwatch with Lap Tracking

Why Use an Online Stopwatch?

While your phone has a built-in stopwatch, an online version has unique advantages:

• Large display — Use your full computer screen for easy reading from across the room.
• No distractions — Unlike your phone, there are no notifications to interrupt your timing.
• Keyboard shortcuts — Start, stop, and lap with keyboard keys for faster operation.
• Classroom/presentation friendly — Full-screen mode is perfect for classrooms, labs, and group timing.
• Always available — Works on any device with a browser. No app to install or update.

Features

• Millisecond precision — Accurate timing down to the millisecond (1/1000th of a second).
• Lap splits — Record individual lap times while the main timer continues running.
• Fastest/slowest highlights — Automatically highlights your best and worst laps in the list.
• Full-screen mode — Expand the timer to fill your entire screen for maximum visibility.
• Clean design — Distraction-free interface focused on the numbers that matter.

Common Uses

• Sports training — Time sprints, intervals, and rest periods. Track lap splits to measure improvement.
• Cooking — Time recipes that need precise durations (boiling eggs, steeping tea, grilling).
• Presentations — Keep track of speaking time during rehearsals and live presentations.
• Games & competitions — Time puzzle-solving, debate rounds, or board game turns.
• Science experiments — Precise timing for lab experiments and observations.

Pro tip: Use the lap feature to track interval training. The fastest/slowest highlight helps you spot your best and worst sets at a glance.

Works Everywhere

The stopwatch runs entirely in your browser. It works on desktop, laptop, tablet, and phone. No installation, no account, no ads. Just open and start timing.
