Fullscreen Stopwatch
About the Fullscreen Stopwatch
A fullscreen stopwatch turns any laptop, tablet, or wall-mounted TV into a dedicated timing board. When the digits fill the display edge to edge, an entire gym, classroom, or finish-line crowd reads elapsed time at a glance without anyone crowding around a phone. That single shared clock changes group behavior: rowers pace to the same number, obstacle-course finishers can self-report times, and workshop cohorts stop asking how long is left in the exercise because the answer covers the wall. This page strips away every toolbar, margin, and menu the moment you enter fullscreen mode, leaving digits sized to the pixel width of the screen.
How to use it
- Open the stopwatch on the device connected to the big screen.
- Click the fullscreen control or press F to fill the display edge to edge.
- Start the clock with a tap or Space at the event cue.
- Operate start, stop, and lap from the front while digits face the room.
- Press Escape to exit fullscreen; recorded laps remain available.
Good to know
The stopwatch counts while this tab is open. A slept tab can pause or jump. For a race result you may need to keep the phone unlocked in your hand.
