Full Screen Timer — Big, Distraction-Free Countdown
Set your time and tap full screen for a giant, readable countdown with no ads and no sign-up. Perfect for focus sessions, classrooms, presentations and timing anything from across the room.
About the full screen timer
A full screen timer turns your whole display into one giant, easy-to-read countdown — no clutter, no ads in your face, nothing to distract you. ClockAura's timer goes full screen with a single tap: set hours, minutes and seconds, press the full-screen button, and the digits fill the screen so they are readable from across a room or the back of a classroom. It runs entirely in your browser with no sign-up, and an alarm plays when time is up even if you have switched tabs.
When to use a full screen timer
- Focus sessions where you want zero distractions on screen — just the countdown.
- Classrooms and exams — project a giant timer everyone can read from the back.
- Presentations and talks — keep speakers on time with a clock everyone can see.
- Workshops, workouts and cooking where you glance at the timer from a distance.
- Streaming or recording — a clean, ad-free countdown on a second screen.
- Any time a tiny phone timer is too small to see across the room.
