## Frequently Asked Questions

### How accurate is the stopwatch?

Our stopwatch uses high-precision JavaScript timing APIs, accurate to milliseconds. It's suitable for general timing needs, though professional sports timing may require specialized hardware.

### What are lap times?

Lap times record split times without stopping the main timer. Click 'Lap' to mark a point in time while the stopwatch continues running. Perfect for tracking intervals or segment times.

### Will the stopwatch keep running if I close the browser?

No, the stopwatch runs in your browser and will stop if you close the tab or browser. For long timing sessions, keep the tab open and ensure your device doesn't sleep.

### Can I export my lap times?

Yes. Copy all lap times to the clipboard with one click, then paste them wherever you need them. There is no file download.

### Does the stopwatch work offline?

Yes, once loaded, the stopwatch works completely offline. All timing happens locally in your browser without any server communication.

### Is there a limit to how many laps I can record?

There is no hard limit. You can record hundreds of laps in a single session. The lap table scrolls automatically so older entries remain accessible.

### Can I use keyboard shortcuts to start and stop?

The stopwatch is driven by its on-screen buttons: Start, Pause, Lap and Reset. There are no keyboard shortcuts for them.

### Does the stopwatch drain my battery?

The stopwatch reads the wall clock rather than counting ticks, so the elapsed time stays correct even when the browser throttles a background tab.

### Is my timing data sent to a server?

No. All timing and lap data stays entirely in your browser. Nothing is uploaded, and no account or signup is required.

### What is the difference between a stopwatch and a countdown timer?

A stopwatch counts upward from zero to measure elapsed time, while a countdown timer counts downward from a set duration. Use our Countdown Timer if you need to track time remaining.
