Use Cases for the Full Screen Countdown Timer

One timer, dozens of jobs. Pick your use case and start counting down in seconds.

Countdown Timer for OBS and Live Streams

Paste any FullScreenCountdown URL into OBS as a Browser Source. Pick a chroma key theme or enable a transparent background for a clean overlay on Twitch, YouTube, or Kick. Mirror mode flips digits for camera-front teleprompter setups. No plugin, no install — the timer runs in OBS just like a webpage.

Countdown Timer for Classroom and Smartboard

Project the timer on a smartboard or projector. Digits scale to fill any screen, readable from the back of the room. Works on school Chromebooks with no signup. Perfect for timed exams, group activities, classroom rotations, and Pomodoro study sessions.

Countdown Timer for Presentations and Stage

Keep your keynote, talk, or pitch on track. Open the mini remote control window on your laptop and the giant timer on the projector. Use the share-link to hand the controls to a stage manager. Adjust the alert beep volume to your room.

Pomodoro Timer Full Screen

Use the 25-minute preset, enable Auto-Repeat, and let the timer restart automatically for each work sprint. Combine with the speech synthesis for spoken time reminders. Works offline as a PWA so it stays open across reboots.

Workout and Interval Timer

Set any duration, repeat it for HIIT circuits, yoga flows, stretching routines, or warmups. The full screen countdown timer keeps every rep visible from across the gym.

Birthday, Wedding, and Event Countdown

Use Target Time with a future date and the timer counts down to the day, hour, minute, and second. Share the URL so guests can watch the moment arrive together.

New Year Countdown Timer

Set a target for midnight on December 31st. Confetti fires automatically when the timer hits zero. Mirror mode and chroma themes work for parties and broadcast.

Exam and Test Timer

Set a fixed duration, project on the board, and forget about it. The audible alert rings when time is up. Press R to reset for the next cohort.

Meeting Timer (Agenda Watch)

Keep meetings short. Set 15 minutes, project the timer on screen, and let participants self-regulate. The mini remote control lets you reset from your laptop without touching the projector.
