How to play

  1. Pick a mode from the tabs — Count up, Countdown, EMOM or Interval.
  2. Fill in the fields that appear for that mode (only the relevant ones show).
  3. Tap Go Full Screen — the clock fills the display with huge, high-contrast digits.
  4. Listen for the buzzer at each mode's boundary: EMOM bells every interval, Interval alternates work/rest, Countdown ends at zero.

A wall display needs to do one thing well: be readable from the back of the room while switching cleanly between whatever the class needs next. Choose from four modes with the tab strip — Count up for an open-ended stopwatch, Countdown for a fixed session length, EMOM for bell-every-interval training, or Interval for a work/rest split with rounds — and only the fields that mode actually uses appear below it. Tap Go Full Screen and the clock fills the display with digits sized for a projector, high-contrast on a dark background, plus a buzzer at every meaningful boundary: the top of each EMOM interval, every work/rest switch, and session start. Switching modes always resets the display cleanly, so there's never a stray timer running behind the scenes.

Frequently asked questions

How is this different from the EMOM Timer or For-Time tools?
Those are dedicated single-purpose timers. This wall display is a multi-mode aggregator built specifically for a big screen: one tool with a mode switcher covering count-up, countdown, EMOM and interval, so a gym doesn't need four different tabs open on the projector.
What happens if I switch modes while the clock is running?
Switching modes immediately stops whatever timer was active and resets the display cleanly to the new mode's starting state — there's never a leftover countdown or bell firing from the mode you just left.
Does Count up mode ever end on its own?
No. Count up is an open-ended stopwatch by design and keeps rising until you tap Exit; Countdown, EMOM and Interval all have a defined finish and end automatically with a fanfare when their configured time or rounds are complete.
