6 tests
Speed tests.
Spot the signal, then act: see how quickly you notice and respond.
Reaction time test
Wait for the circle to fill, then tap as fast as you can. See how quickly you react, in milliseconds.
Start the testClick speed test
Click as fast as you can before the timer runs out. See your clicks per second, from a one-second burst to a full minute.
Start the testSpacebar counter
Press the spacebar as many times as you can before time runs out. Count your presses and see your speed per second.
Start the testSchulte table
Find the numbers in order, as fast as you can, on a scrambled grid. A classic exercise for focus and visual search.
Start the testTrail making test
Connect scattered circles in order as fast as you can: numbers first, then numbers and letters in turn.
Start the testStroop test
Name the color of the ink, not the word. See how much a mismatched word slows you down, in milliseconds.
Start the testChoose a speed challenge
The speed collection covers different kinds of quick response. The reaction time test measures how fast you respond to a single signal. The click speed test and the spacebar counter count how many presses you can make in a set time. The Schulte table and the trail making test time a visual search through numbers and letters, and the Stroop test measures how much a conflicting word slows you down.
Your hardware and browser affect every timed result, so compare runs on the same device, with the same input method and settings. Each score describes one task, rather than a measure of every kind of speed.
