The tests
Speed is not one skill, so each test looks at a different part of it.
- The reaction time test waits for the screen to turn green and measures how many milliseconds you need to click.
- The typing speed test gives you random everyday words and shows your words per minute and accuracy.
- The CPS test counts how many times per second you can click in a short burst.
- The audio reaction time test swaps the colour change for a beep.
- The choice reaction time test adds a decision: press the matching side, or hold back when you should not press.
- The aim test shows targets one at a time and measures how fast and how cleanly your hand follows your eyes.
- The finger tapping test times how fast and how evenly you tap with one finger.
- The time perception test asks you to stop an invisible timer at a set moment.
- The hand tremor test gives you a relative score for how still you can hold a fingertip or cursor on a dot.
Get a fair result
- Use the same device every time. Screens, mice, keyboards and touchscreens each add their own delay, often 20 to 60 milliseconds, which is part of every online result.
- Warm up with a round or two, then judge yourself on the average, not on one lucky try.
- Sleep, caffeine, alcohol and time of day all change your speed, so compare results taken in similar conditions.
