Timing Test
A dot vanishes behind a cover — press the instant it should cross the line.
Press here when the dot hits the line
The dot slides behind a cover — press the moment it crosses the line.
- The dot slides in from the left at a steady speed.
- It disappears behind the grey block; keep it moving in your head.
- Press the screen when it should be on the white line. Closer is better.

Do not count a beat — watch it slide.
First time here? A first round often lands between 60 and 120 ms — three unscored practice goes come first.

How to read your score
| Score | What it means |
|---|---|
| Under 40 ms | A timing test average miss under 40 ms across 12 presses is this test's most accurate band: you landed on the line almost every time. That's near the limit a touchscreen and browser can measure, so it reflects a steady device as much as a steady hand. It's a range on this test, not a ranking. |
| 40 to 65 ms | A timing test average miss of 40 to 65 ms across 12 presses is a tight band on this hidden-dot game. Check your direction: a small miss that's consistently early or late means your sense of speed is right and you just press at a fixed offset - the easiest thing to fix. |
| 65 to 95 ms | A timing test average miss of 65 to 95 ms across 12 presses is the middle of this test's five bands, and a common spot for a careful first round. It shows how big the miss is, not which way: see the direction line for early or late, and the twelve bars for each press. |
| 95 to 140 ms | A timing test average miss of 95 to 140 ms across 12 presses usually means a few presses were clearly early or late. Look at the chart: a few long bars among short ones often come from counting a beat instead of watching the dot. |
| 140 ms or more | A timing test average miss of 140 ms or more across 12 presses means you hadn't found a steady feel for the timing yet. At the fastest speed the dot is hidden for only about 0.4 seconds, so this miss is most of that stretch. If it was your first round, play again once the practice goes feel familiar and compare. |
These five bands are ranges for this site's version of the test; a smaller average miss is better. They aren't percentiles or pass marks and don't say how many people you beat - there's no reference data yet. Twelve presses pin your score down to within about 20 to 25 milliseconds, which is why no band is narrower than 25 milliseconds: a round can move that much on its own. So look at several of your own rounds on the same device, pressing the same way, and treat a change smaller than one band as no change.
How to play
- Look at the track before you start: The ready screen shows the track you'll play on: a thin line, a grey block over its last third, and a white finish line on the right. It never moves or resizes during a round.
- Take the three practice goes: First come three practice goes, one at each speed. Each tells you how early or late you were in milliseconds - the only feedback you'll get. They don't count. Press Continue to start scoring.
- Watch the dot, do not count: The dot waits on the left for 0.6 to 1.2 seconds, then moves at a steady speed. The wait changes every time, so counting a beat makes you less accurate - just watch it.
- Press when it should cross the line: The dot vanishes as soon as it reaches the grey block; carry it the rest of the way in your head. Press anywhere in the big area below the track - no need to hit the dot. Only your first press each go counts.
- Read your average miss and your direction: Your big number is how far off your presses were on average, in milliseconds - lower is better. Below it: whether you tended to be early, late or neither. The twelve bars are your twelve scored goes, early to the left and late to the right, with a dotted row for any go you didn't press.
Full rules
This is a non-standardised adaptation, and the result cannot be exchanged with a clinical scale or an instrument reading. A round is 3 practice goes and 12 scored ones. Each go, the dot starts on the left and moves at a steady speed until it disappears behind a grey cover over the last 35 percent of the track. Press at the instant it would cross the white finish line.
This is about predicting, not reacting: when you press, you can't see the dot, so you have to keep it moving in your head. Researchers call this kind of task coincidence anticipation timing or prediction motion; this version, its speeds and its bands are the site's own.
There are three speeds, four scored goes each. Even at the same speed the travel time varies a little, and the wait before launch changes every time - none of it shown on screen. So don't count; judge each go fresh from the dot.
Your score is your average miss over the 12 scored goes - how many milliseconds off each press was, ignoring early or late. Lower is better; a perfect press is zero. Early or late is shown separately as your direction, because always 60 ms early and randomly 60 ms off are very different.
One unusually bad press may be left out of the average; the result card says how many were. Left-out presses still appear in the chart as hollow bars, so all twelve keep their place. To compare rounds, use the same device and press the same way.
Pressing before the dot reaches the cover, or within 100 milliseconds of it, is a false start - too soon to be a real judgement. Not pressing at all is a miss. Either way that go doesn't count and isn't replayed; the reason shows under the track and its row in the chart is a dotted line.
If three goes in a round can't be used - false starts, misses or device stalls - the round ends without a score and you can play again. Zooming the page mid-round ends it too, because the track has to stay the same size.
Practice goes tell you right away how early or late you were. The 12 scored goes don't - your score appears once all twelve are done, so just press on your own judgement.
Compare your own rounds, not other people's. Both figures are shifted as a block by this device's and browser's display latency, so compare them only with your own earlier rounds on the same device. A device delay shifts every press by the same amount, so phone and laptop scores can't be compared.
Stay on this page until the round ends. Switching tabs, refreshing or stopping means the round doesn't count and nothing is saved - there's no resume. All that's saved is a few times and the twelve misses that draw the chart, and it stays in your browser.
FAQ
What is a timing test?
It tests how accurately you can time an action to a moment, rather than how fast you react. Here a dot moves along a track, disappears behind a cover for the last third, and you press the instant it should cross the finish line. Your score is how far off you were, in milliseconds, averaged over twelve presses.
What is anticipation timing, and how is it different from reaction time?
Anticipation timing means acting at a moment you've predicted; reaction time means acting as fast as you can once something appears. A reaction time can only be positive, but a timing miss can be early or late - and you can't be early in a reaction test. That's why this page shows a direction as well as a size.
What is a good score on a timing test in milliseconds?
On this test, an average miss under about 65 milliseconds over twelve presses is tight, and lower is better. It can't tell you where you stand among other people, because there's no reference data. Check the five bands, then compare several of your own rounds on the same device.
Why does the dot disappear in this timing test?
Because if you could still see it, it would be a reaction test. Hiding the last stretch makes you keep the dot moving in your head and press where it is now - that's the whole game. The cover is drawn on the ready screen too, so the first disappearance never looks like the page froze.
Why am I always pressing early or late on the timing test?
A one-sided bias means you press at a fixed offset, and the result card tells you which way. Pressing early usually means you're going by the dot's last visible spot instead of carrying it across the hidden stretch; pressing late usually means you're waiting for a sign it arrived, and the track never gives one. A one-sided bias is the easier problem, because most of your miss is one steady offset.
How do you get better at a timing test?
Work on the two parts separately: correct an early or late bias by nudging your press the other way next round, and reduce scatter by watching the dot right up to the cover instead of counting. The speeds are mixed and the waits vary, so memorising a rhythm won't help. Practice makes you better at this game - the evidence that it carries over to anything broader is weak (Simons et al., 2016).
How much does a timing test score change between rounds?
Expect your average miss to move by about 20 to 25 milliseconds between rounds even if nothing has changed: twelve presses are enough to place you in a band, not to show finer differences. So a round 15 milliseconds better than your last isn't an improvement yet, but several rounds settling into a lower band is. Keep the device and the way you press the same.
Why did my timing test round give no result?
A round doesn't count if three of its goes couldn't be used, or if the page lost focus, was zoomed or stalled badly enough to throw off the timing. False starts and goes with no press both count toward those three, and the screen says which happened. Rather than show an unreliable number, the page offers you another round.
Can a timing test on a phone be compared with one on a laptop?
No, and the result card says so. Every device and browser adds its own display and input delay, which shifts every press by about the same amount and moves both your average miss and your direction. Compare phone rounds with your earlier phone rounds, and keep laptop rounds separate.
