Displays reconnect and pick the exam back up automatically when the network returns. No refresh, no restart.
Nothing to install
TVs, projectors, tablets, phones - if it can open a link, it can run an exam. No apps, no IT tickets.
Instant everywhere
Change anything on one device and every display follows immediately. One invigilator can run the whole hall.

Four Ways to Time an Exam Hall
Schools and universities usually pick one of these. Three fall apart the moment one candidate has extra time - here's the honest comparison.
Whiteboard + wall clock
GoodFree, familiar, and it can't crash.
Trade-offsOne time for the whole room - extra-time candidates get hand-done arithmetic on the board, every change means rewriting it mid-exam, and nothing is logged.
PowerPoint countdown slides
GoodTools every staff room already has, and it looks tidy on a projector.
Trade-offsOne timer per deck, so extra time means separate laptops. Editing mid-exam stops the show, and a sleeping laptop freezes the clock.
Generic online timers
GoodOne click and a countdown is on the screen.
Trade-offsA single countdown with no exam details, no per-candidate clocks, and no sync - each screen is set by hand and drifts on its own.
ExamClock
GoodEvery candidate's clock calculated for them - 10%, 25%, or 50% extra time and rest breaks - on displays that stay in sync and survive wifi drops.
Trade-offsThe hall screen needs a browser and a link. The free plan runs one exam session at a time - Pro is $89/year.

Yes. Pause that student's clock and resume it when they're back - every break is logged. Rest breaks →
