Frequently Asked Questions
- How precise is the stopwatch?
- The display updates every 100ms (tenth of a second). Internally it uses Date.now() for accuracy, so it compensates for timer drift.
- Will the countdown alert work if I switch tabs?
- The timer continues counting in the background. The audio alert plays when you return to the tab — browsers may throttle timers in background tabs.
- Is anything stored or sent?
- No. The timer runs entirely in your browser with no server communication.
