How to use
- Choose a quick preset (1, 5, 10 or 25 minutes) or type your own hours, minutes and seconds.
- Press Start. The display counts down and shows the exact clock time when it will finish.
- When the timer reaches zero you hear a beep and the card flashes so you do not miss it.
- Turn on Repeat mode for workouts or intervals, and press Reset anytime to start over.
Tips
- Keep the tab open or pinned — the beep plays even when you are working in another window.
- Use the 25 minute preset for focus sessions, and the repeat mode for study breaks.
- Glance at the end time to plan your schedule around when the timer finishes.
- For cooking, set the timer a minute early so the beep gives you time to react.
