Question 3

Why does my timer drift slightly?

Accepted Answer

This timer uses performance.now() for high-precision timing, synchronized against actual elapsed time every tick. Unlike setInterval (which can drift by 10–50ms per second), our approach re-calculates the remaining time from the actual start timestamp each frame, ensuring accuracy regardless of background tab throttling. The displayed time is always mathematically exact.

Question 4

What is the Pomodoro Technique and does it actually work?

Accepted Answer

The Pomodoro Technique uses 25-minute focused work sessions followed by 5-minute breaks. After 4 sessions, take a 15–30 minute long break. Research on time-boxing shows: context switching costs 15–20 minutes of recovery time. Regular breaks prevent decision fatigue. The 25-minute interval aligns approximately with natural attention cycles for most adults. Individual optimal intervals vary — some people work better with 50/10 or 90/30 cycles.

Question 5

How accurate is a browser-based timer?

Accepted Answer

Browser timers using setInterval can drift significantly because JavaScript is single-threaded. Browser tabs also throttle timers when in the background. This tool uses performance.now() and anchors elapsed time to a real start timestamp — each tick calculates remaining time from actual elapsed milliseconds rather than accumulating increments. This eliminates drift almost entirely, even in throttled background tabs.

Question 6

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

Accepted Answer

A stopwatch counts up from zero and measures elapsed time (how long something took). A countdown timer counts down from a set duration and alerts when time runs out. This tool includes both modes, plus lap recording for the stopwatch, Pomodoro mode with session tracking, and multiple simultaneous countdown timers — each with its own progress bar and sound alert.

Question 7

How do I time a presentation to stay within limits?

Accepted Answer

1 minute of relaxed speech ≈ 100–150 words. A 10-minute presentation needs approximately 1,000–1,500 words of script. Set this countdown timer with your time limit. The colour changes from blue to yellow at 20% remaining and to red at the final 10 seconds — built-in visual warnings without distracting the audience. Leave 10–15% of your time for Q&A if required.
