AMRAP Timer

AMRAP means As Many Rounds As Possible — sometimes As Many Reps As Possible — within a fixed time cap. You are given a sequence of movements and a clock, and your score is how many full rounds, plus any leftover reps, you complete before time is called. This timer counts down a 20-minute cap by default and opens fullscreen-first, so the number stays legible from across a gym floor with your phone propped on a bench. It is a staple of CrossFit and conditioning classes because it is brutally simple to score and scale: everyone runs the same clock, and the workout meets each person at their own capacity. A newer athlete and a seasoned one can do the identical AMRAP and both get a hard, honest effort out of it. How you run it matters more than how hard you start it. The classic mistake is going out far too hot — hammering the first three rounds, then falling apart and spending the back half gasping between reps. A good AMRAP is paced almost like a time trial: settle on a round time you can genuinely repeat, and aim to hold or even slightly quicken it as the clock winds down. Consistent rounds almost always beat a fast start followed by a collapse. The non-obvious tip is to stop trusting your memory. Under fatigue, round counts evaporate — people routinely lose track by round eight and either short themselves or claim rounds they did not finish. Keep a physical tally: move a token, make a chalk mark on the floor, or flip a plate each round. It sounds trivial, but an accurate score is the whole point of an AMRAP, and your brain at minute 15 is not a reliable counter. On alerts: the finish alarm is loud and fires reliably while this tab is open, which is what you want when the clock runs out mid-rep. Keep the tab in the foreground on your propped phone — switch away and the alarm can arrive up to a minute late, and close the tab and it will not sound at all, since nothing runs server-side. On iPhone, flip the side mute switch off or the cap will pass in silence.

Frequently asked questions

What does AMRAP stand for?
As Many Rounds As Possible — or As Many Reps As Possible — within a set time. You repeat a fixed sequence of movements and count how far you get before the clock hits zero.
How is an AMRAP scored?
By the number of complete rounds you finish, plus any additional reps into the next round — so a score might read "12 rounds + 8 reps." Keeping an accurate count during the workout is essential.
How should I pace it?
Steadily. Pick a round pace you can sustain for the whole cap rather than sprinting the first few rounds. Even or slightly negative splits — finishing faster than you started — almost always beat going out too hard and fading.
Can I change the time cap?
Yes — set any countdown length before you start. Common caps run from 5 to 20 minutes. Use the copy-link button to share the exact cap with training partners.
Will the final alarm fire if I set my phone down and it locks?
While this tab stays open the alarm is reliable, though a backgrounded tab can delay it by up to a minute. A closed tab will not alert you at all — there is no server behind the timer. On iPhone, keep the side mute switch off so the alarm actually sounds.

This timer keeps the exact time even if you switch tabs. If this tab or your browser closes, nothing can alert you at the exact finish time — there's no server behind this, by design. Come back any time and we'll tell you honestly how long ago it ended.
