Free Online CrossFit Timer

Choose the clock that matches the workout you already have. This CrossFit timer brings EMOM windows, an AMRAP countdown, a For Time stopwatch, and repeating work/rest intervals into one browser tool.

One CrossFit clock, several timing models

A workout format tells you what the clock measures. Some formats give you a fixed time window; others ask you to measure the time needed to finish a predefined task. A CrossFit workout timer needs both countdown and count-up behavior because those instructions are different. Select a mode using the buttons above the clock, then check its fields before starting.

The hub is useful when your sessions use several formats and you want a familiar place to operate each clock. It does not combine those formats into a training plan. Your movements, repetition counts, and stopping rules come from the routine you have chosen. Dedicated EMOM, AMRAP, and Tabata pages remain available below for a focused setup.

Match the mode to the instructions

Read the timing instruction before choosing a mode. “Every minute” needs repeated boundaries, “ten minutes of work” needs a fixed countdown, and “finish this sequence” needs an elapsed clock. Work/rest instructions need alternating phases. The selected mode controls what the large digits mean.

EMOM: repeated windows

EMOM starts a new interval at each scheduled boundary. The default interval is sixty seconds, and the interval length can be changed. The timer does not automatically detect when you finish the work inside a window; it continues to the next boundary.

AMRAP: a fixed window

AMRAP counts down from the duration you choose. Its round counter is a manual record of completed work, separate from the countdown. Adding a recorded round does not restart the clock or create a new interval.

For Time: elapsed duration

For Time counts upward from zero after any preparation period. Press Finish when the predefined task is done. Pause excludes the paused period from elapsed time, so decide in advance whether your timing rules permit a pause.

Tabata / Interval: alternating phases

This mode repeats work and rest for a set number of rounds. The 20/10 example uses eight rounds and includes the final rest. Other values create a custom interval clock; choosing the mode does not make every workout a Tabata session.

How to get started with the CrossFit timer

Select one mode, enter the relevant duration and count, and review the preparation setting. Start begins preparation when it is enabled; otherwise the main clock starts immediately. Keep the sound switch on if you want audible transitions and check the device volume. Fullscreen enlarges the active clock without changing its timing model.

Pause freezes the logical clock, and Resume continues from that point. Finish belongs to the For Time stopwatch; Skip belongs to clocks with scheduled phases. Skip advances to the next phase rather than counting a completed exercise. Reset clears the active timing state. Mode buttons remain locked during running and paused sessions until you finish or reset, preventing an accidental change of clock.

A hub or a dedicated timer?

Use this CrossFit interval timer hub when you need to move between formats across separate sessions. Choose a dedicated page when you repeatedly use one format or want its detailed explanation. The engines follow the same timing rules in both places, but hub settings are stored separately so experiments here do not replace your dedicated timer setup.

A circuit timer is useful when station names and station transitions are part of the schedule. A workout timer suits an ordered timeline with different segment lengths. HIIT describes a broader interval context, while Tabata identifies a particular timing format. Those pages solve different setup tasks and are linked alongside the mode pages, rather than hidden inside a crowded selector.

Saving a setup and keeping the clock visible

The save action stores settings in this browser. Each hub mode has its own saved list; switching modes does not transfer a duration into another format. A share link includes timer settings and unit choices, not session results or saved setup names. Opening a valid hub link selects the matching mode. Avoid placing personal details in anything you share.

Browser callbacks can arrive late in a background tab. Countdown modes calculate from deadlines; the elapsed clock calculates from timestamps instead of adding one second per callback. This helps the display catch up when the page becomes active. Device sleep, browser suspension, muted output, and unavailable audio APIs can still interrupt cues. Keep the page visible when transitions matter, and do not treat this training clock as certified competition timing.

Frequently Asked Questions

Practical answers about how this timer format works.

Does this CrossFit timer choose a workout for me?

No. It supplies clocks for a routine you already selected. Presets demonstrate timer controls and common timing structures; they do not prescribe movements, intensity, rest needs, or a target result. Choose the clock from your existing instructions.

Should I select AMRAP or For Time in the hub?

Choose AMRAP when the time window is fixed and you record the work completed before it expires. Choose For Time when the task is fixed and you measure how long completion takes. A countdown and an elapsed stopwatch answer different questions.
