The Free WOD Clock Built for Serious CrossFit Athletes
A WOD clock — short for Workout of the Day clock — is the single most important piece of equipment in any CrossFit box that doesn't require bolts in the wall. Professional CrossFit gyms invest in dedicated hardware gym clocks because athletes need a large, unambiguous countdown visible from anywhere on the training floor, audio cues that pierce through music and heavy breathing, and clear round tracking for complex interval structures. This free online WOD clock delivers all of that in a browser-based format that works on any device — from a phone propped on a weight rack to a laptop connected to a large display for an entire class. No app required, no subscription, no account — just the modes you need and a display that performs under intensity.
AMRAP: As Many Rounds As Possible
AMRAP is the most common WOD format in CrossFit programming. You set a time cap — typically 10, 15, 20, or 25 minutes — and perform as many complete rounds of a movement complex as possible before time expires. Your score is the number of completed rounds plus any additional reps in an incomplete round at the bell. Famous benchmark AMRAPs include Cindy (5 pull-ups, 10 push-ups, 15 air squats for 20 minutes) and Murph (1 mile run, 100 pull-ups, 200 push-ups, 300 squats, 1 mile run — though technically a For Time workout). The AMRAP mode on this clock counts down from your set duration, plays a loud triple beep at the end, and flashes a completion signal. Use the Next Round button to manually increment your round counter and track your total without losing focus on the movement.
EMOM: Every Minute On the Minute
EMOM workouts are one of the most versatile training structures in functional fitness. At the top of each new minute, you perform a specified number of reps of a movement. The remaining seconds of that minute are your rest. The density of work — the ratio of work time to rest time — can be adjusted by changing either the reps or the movement. As you get fitter, you complete the reps faster, giving yourself more rest. If the reps start taking the full minute with no rest, it's time to scale down or increase your capacity. This clock's EMOM mode beeps loudly at the start of each interval and increments the round counter automatically, so you always know which minute you're in. The total minutes setting lets you run anything from a 5-minute skill primer to a 30-minute conditioning piece.
Tabata: The Classic HIIT Protocol
Tabata training was developed by Dr. Izumi Tabata at the National Institute of Fitness and Sports in Tokyo. The original protocol — 20 seconds of maximum intensity work, 10 seconds of rest, repeated 8 rounds for 4 minutes total — was shown in research to produce improvements in both aerobic and anaerobic fitness simultaneously in just 4 minutes of actual work. In CrossFit, Tabata is often applied to single movements (Tabata Squats, Tabata Pull-Ups) or to multiple movements in succession. This WOD clock automates the entire Tabata sequence: it beeps distinctly for work and rest phases, tracks current round out of total rounds, and counts down the remaining time in each phase. The default setting matches the original protocol, and all parameters — work time, rest time, and total rounds — are adjustable for custom Tabata variations. Pair this with our dedicated Workout Timer for non-CrossFit interval training needs.
For Time: Racing Against the Clock
For Time workouts are the purest expression of CrossFit's competitive spirit: complete the prescribed work as fast as possible. Your score is your finishing time. The stopwatch starts and counts up until you hit the finish button or a time cap expires. Famous For Time workouts include Fran (21-15-9 thrusters and pull-ups), Grace (30 clean-and-jerks for time), and the Filthy Fifty (50 reps each of 10 movements). The For Time mode on this clock counts up from zero, displaying elapsed time in large digits. Set a time cap if your programming includes one — the clock will count up normally but transition to a cap-exceeded alert if you haven't finished by the cap. Press Reset to discard the time or stop the clock when you complete the workout.
3-2-1 Countdown: The Pre-Workout Mental Cue
The 3-2-1 countdown before a WOD serves a physiological and psychological purpose. It gives athletes time to take a final breath, assume their starting position, and mentally commit to the intensity they're about to bring. The countdown also creates a shared moment of anticipation that transforms solo training into something that feels like competition. This WOD clock plays a 3-2-1 countdown sequence before every workout when the countdown option is enabled. Each count plays a distinct audio beep. When the final count fires, the main timer begins automatically — no additional button press needed. For strength work with built-in rest intervals, combine this clock with our Boxing Timer or Plank Timer for core conditioning work.
Using the WOD Clock for Gym Classes and Group Training
CrossFit coaches and personal trainers use browser-based WOD clocks because they're instantly accessible on any device without software installation or licensing fees. Connect a laptop to your gym's TV or display using HDMI, open the WOD clock, set your format and duration, and every athlete in the class can see the countdown. The large, high-contrast display is readable from across most box sizes. Audio cues provide auditory feedback for athletes whose backs are turned or who are looking down at a barbell. The pause and resume buttons give coaches full control over the training session — easily pause for technique corrections, athlete questions, or equipment changes without losing the current round count.
Works on Any Device — No App Required
This WOD clock runs entirely in your browser on any modern device. Use it on a phone propped beside your training area, on a tablet mounted to a rack, on a laptop connected to a gym display, or on any screen where you need a reliable, professional countdown. No installation, no subscription, no account. The Space bar shortcut lets you start and pause without touching the screen mid-workout. Browser notifications fire on completion even when the screen goes dark. Everything is completely free — professional-grade WOD timing accessible to everyone from garage gym athletes to commercial CrossFit boxes.
