Built for the interval clock

Intervals are the backbone of conditioning: fixed work, fixed rest, on repeat. Rowing repeats, bike erg pieces, station circuits where the whole floor rotates on the beep — they all live and die by a clock everyone can see and hear.

Set the work window (up to an hour), the rest, and the rounds. The ring flips color between work and rest, round pips track progress, and the rest screen shows what’s next so nobody has to shout station changes over the music.

How it works

  1. Set work and restAnything from :01 to 60:00 each — 3:00 on / 1:00 off for engine work, :40/:20 for circuits.
  2. Set the roundsUp to 99, with round pips across the bottom of the screen.
  3. See what’s nextDuring rest the screen shows the next block, so station rotations run themselves.
  4. Put it on the TVFullscreen in the TV’s browser — no install, no app, no dongle.

The clock that wears your box.

  • Your name, your colors, your logo across the top of every screen in the gym — the timer becomes yours at yourbox.wodfoundry.com.
  • Athlete demos on the clock — male and female athletes demo air squats, deadlifts, burpees, and thrusters inside the ring while the class works.
  • A custom demo athlete or mascot rendered in your gym’s kit — one-time add-on, yours forever.
  • The custom-workout builder + saved timers — coaches build the day’s piece once and it’s on every screen.
  • Unlimited devices, no limits — every TV in the box and every coach’s phone.

Interval timer FAQ

What’s the difference between intervals and EMOM?

EMOM fixes the start of each work bout to the clock (top of every minute); intervals fix the work and rest durations themselves — 3:00 on, 1:00 off, for example. This timer does both: this page’s format for work/rest pieces, and a dedicated EMOM format for on-the-minute work.

Can I use it for station circuits?

Yes — set the work window to the station time and the rest to the transition time. The rest screen shows what’s next, so the floor rotates without the coach shouting.

How loud are the alerts?

The end-of-interval alert is a real gym-grade beep (or a spoken countdown) played through whatever the TV’s plugged into. It’s built to beat barbells and playlists.

Is the interval timer free?

Yes — free at wodfoundry.com/timer, capped at 10 minutes per free run. Gyms on the $29/mo plan get unlimited runs with their own name, colors, and logo on the clock.
