Measure your reaction time in milliseconds. Train reflexes, focus and attention.
How many milliseconds does it take you to react? Train your reaction time, reflexes and concentration with short exercises that take a few minutes a day. 13 exercises train response speed, attention and visual memory. Every result is recorded in milliseconds along with your mistake count, so progress shows up directly in numbers instead of vague feelings. FEATURED EXERCISES Schulte Table Tap the numbers from 1 to 25 in order. The trick is to keep your eyes still and take in the whole grid with your peripheral vision. It is the classic drill for focus and speed reading, and the grid grows larger as you progress. Colored Text (Stroop test) The name of a color appears printed in a different color. You have to hold back the urge to read the word and answer quickly by the real color. The best known test of selective attention. Peripheral Vision Hold your gaze on the mark in the center and tap the spot that flashes at the edge of the screen, without moving your eyes. Math Mental arithmetic under time pressure: pick the correct answer as fast as you can. ALSO INCLUDED Change color, Catch the ball, Catch the color, Find color, Find a number, Comparison of numbers, Equal numbers, Swipe, and Go / No-Go, which trains impulse control: tap on green, hold back on red.
