ClockKeepers

ClockKeepers is the timer the whole room can see.

Start a countdown, stopwatch, or interval program on your phone, tap Broadcast, and every phone, tablet, or TV browser that opens your link shows the same clock, live, in sync, with the phase colour and round count. No mirroring, no cables, no app needed on the big screen: open clockkeepers-app.netlify.app on any TV browser and type the 5-letter code.

BUILT FOR REAL ROOMS • Gyms & studios: Tabata, HIIT, EMOM, AMRAP, boxing and MMA rounds, "For time" with a cap. Work and rest flood the screen green and red so nobody has to squint. • Classrooms: 5/10/15/20-minute periods, Pomodoro, a speech timer that turns amber and red as time runs out. Control it from your phone while you walk the room. • Courts & tournaments: round clocks with changeover breaks, "Round 3 of 8", one board for every court. • Home: kids' turns, cooking, board games. Free, forever.

WHY COACHES AND TEACHERS SWITCH • Broadcast to any screen with a link, QR code, or short code. Viewers never install anything. • Sound that actually plays: 3-2-1 beeps, segment tones, finish alarm, and a spoken countdown, even with the silent switch on. • The screen never sleeps while a timer runs, and a notification fires if the app is in the background when time is up. • Lets others control the clock (optional): pass the link to an assistant coach and either of you can pause. • Custom interval builder: up to 12 segments per round, 99 rounds, a get-ready period, labels and colours. • Presets for the programs people actually run. One tap and go. • Session log of what you ran and for how long. • On an iPad, run the timer and the controls side by side, or tap Present to fill the screen. • AirPlay or plug into a TV: the board fills the screen and the controls stay on your device. • No ads. No subscription. No account.

CLOCKKEEPERS PRO (one-time purchase) • Up to 8 timers on one board: stations, courts, or groups, with Start all / Pause all, laid out automatically on the TV. • Your gym, class, or event name, colours, and logo on every screen. • A permanent code (like "ironworks") so the TV bookmarks one link forever. • Nine more display themes: LED, Stadium, Neon, Chalk, Minimal, Sunset, Aurora, Dot Matrix, Blueprint. • Sound packs: gym horn, ring bell, whistle, arcade. • Unlimited viewers, saved presets, and session history. No watermark.
