Buyer's guide
How to choose a stopwatch
When picking a stopwatch, consider whether you need to record split or lap times during a single session. If you only need to start, stop, and see total elapsed time, a simple digital counter like RapidTables suffices. If you need to track cumulative segment times β for example, splitting workout rounds or measuring intervals in a long event β choose a tool with lap timing support, such as TimeAndDate.
Questions
Stopwatch FAQ
- Can I use these stopwatches on a mobile phone?
- Yes, all three tools are web-based and work in mobile browsers. RapidTables and TimeAndDate adapt to screen size, while White Screen is designed for fullscreen mode on any device with a browser.
- Do these stopwatches require any installation or download?
- No installation is needed. RapidTables, TimeAndDate, and White Screen all run directly in your browser without requiring any software download or account creation.
- What is the smallest time unit these stopwatches can measure?
- RapidTables measures to hundredths of a second, TimeAndDate provides millisecond precision, and White Screen uses flip-clock digits that count up from zero in seconds, minutes, and hours.
- Can I record lap or split times with these tools?
- TimeAndDate supports lap timing, allowing you to record cumulative or segment times without stopping the main timer. RapidTables and White Screen do not have built-in lap tracking functionality.

- There is no stated time limit for any of the three tools. They can run continuously for extended periods, though White Screen is designed with a fullscreen overlay that ends when the tab is closed.
