❓ Frequently Asked Questions
What's the difference between stopwatch and timer modes?
+
Stopwatch mode counts up from zero, measuring elapsed time - perfect for timing workouts, races, or tasks. Timer mode counts down from a set time to zero with alerts - ideal for cooking, study sessions, breaks, or reminders. Both modes offer precise timing with millisecond accuracy.
How accurate is this timer and stopwatch?
+
Our timer is highly accurate, displaying time to the centisecond (hundredths of a second). It uses JavaScript's high-resolution timing APIs for precision. While browser-based timers can have minor variations due to system load, they're accurate enough for most practical purposes including sports timing and cooking.
Can I use this timer with the browser tab closed or minimized?
+
The timer continues running when the tab is minimized, but browsers may throttle background tabs to save resources, potentially affecting accuracy. For best results, keep the tab active. When the timer reaches zero, you'll get both visual and audio alerts to ensure you don't miss it.
What are lap times and how do I use them?
+
Lap times are split times recorded during stopwatch operation without stopping the main timer. Click "Lap" to record the current time while the stopwatch continues running. This is perfect for interval training, tracking multiple rounds, or measuring segments of longer activities. Each lap shows both the split time and total elapsed time.
Are there keyboard shortcuts for controlling the timer?
+
Yes! Use Spacebar to start/pause the timer, 'R' key to reset, and 'L' key to record a lap (in stopwatch mode). These shortcuts work when the page is focused and make it easy to control the timer without clicking buttons, especially useful during workouts or when your hands are busy.
