Measure the way
your mind works.

Five focused tests for reaction speed, visual memory, number memory, flick accuracy and typing performance. Results are approximate because browser performance, hardware and input devices can affect measurements.

Short tests designed around measurable approximate performance.

01

Reaction Speed

Measures how quickly you respond to a visual signal.

Best:
Wait through an unpredictable delay until the panel turns green, then click immediately. Clicking before the signal is a false start and never becomes a reaction time score hence u get a retry.
02

Gridshot

Measure flick accuracy, target acquisition and hand-eye coordination.

Best:
Hit as many targets as possible in 20 seconds. Gridshot measures target count and flick accuracy. A small crosshair keeps the visual reference precise without covering the target.
03

Visual Memory

Remember increasingly difficult spatial patterns.

Best:
Memorize a group of highlighted locations and produce them after they disappear. Each successful round increases the number of locations.
04

Number Memory

Test how many digits you can hold accurately.

Best:
Memorize a number, enter it after it disappears, and progress to longer sequences. One incorrect sequence ends the run.
05

Typing Speed

Measure WPM and typing accuracy with a timed paragraph.

Best:
Type the displayed paragraph during the fixed test. The passage continues automatically so fast typists cannot run out of text.
