Stopwatch and Timer Guide
When to Use Stopwatch Mode
Stopwatch mode is ideal when you do not know how long a task will take. Start the clock, record laps for milestones, and pause or reset at any time.
When to Use Timer Mode
Timer mode is best for time-boxed activities like study sessions, interval training, cooking, or work breaks. Set a duration, start the countdown, and get a visual completion state when time reaches zero.
Popular Use Cases
- Pomodoro focus sessions (25m work, 5m break)
- Workout intervals and rest periods
