⏲️ Fullscreen Sleep Prevention – Timers That Never Stop
Timers are essential for cooking, workouts, study sessions, public speaking, and more. But with most online timers, your computer will eventually go to sleep if you don't interact with it, and you'll lose track of your countdown.
With our fullscreen timer:
- The timer display stays on for the entire countdown, no matter how long it runs.
- You can focus on your task—cooking, exercising, or studying—without worrying about the screen turning off.
- When the timer ends, you'll see and hear the alert right away, even if you haven't touched your device.
Without this feature:
- The screen may go black before your timer finishes, and you could miss the end signal.
- You might overcook food, miss a workout interval, or lose track of your study session.
Our fullscreen sleep prevention ensures your timer is always visible and your results are always accurate—no interruptions, no surprises.
