Frequently Asked Questions About the Online Work Timer
What is the best timer duration for desk work?
The 25-minute Pomodoro sprint is optimal for routine tasks, email management, and studying. For high-complexity tasks like software programming, data analysis, or creative writing, a 50-minute or 90-minute work block is often more effective.
Does this work timer keep counting if I switch tabs?
Yes. TimerBox computes real elapsed time using millisecond timestamp deltas, ensuring your countdown remains pinpoint accurate even when minimized.
