FREQUENTLY ASKED QUESTIONS
Q1.Does the timer work when I switch browser tabs?
Yes. The timer uses the system clock (Date.now()) to track real elapsed time rather than relying on interval counts alone. Browsers may throttle background tabs, but the timer will still show the correct time because it always checks the actual clock when it wakes up.
Q2.What is a Pomodoro timer?
The Pomodoro Technique is a time management method where you work in focused 25-minute sessions separated by 5-minute breaks. After four sessions, take a longer 30-minute break. Research suggests this rhythm improves focus and reduces mental fatigue. Use the "25 MIN" preset to start a Pomodoro session.
Q3.How many laps can the stopwatch track?
Up to 20 laps. The stopwatch shows each lap's split time (delta from the previous lap) and the total elapsed time at each lap. The fastest lap is highlighted in green and the slowest in red, making it easy to compare performance across laps.
Q4.Does the timer play a sound when it reaches zero?
No — this tool is visual only. When the countdown reaches zero, the display flashes and shows "TIME'S UP" in the terminal. For audio alerts, use your device's built-in timer app (Clock on Android/iOS) alongside this tool if sound is needed.
Q5.Can I set hours on the countdown timer?
Yes. Use the HH segment in the time input to set hours up to 99. You can click the ▲/▼ buttons to increment, or click directly in the field and type a number. Presets cover common durations from 1 minute up to 1 hour.
