Reaction Time

Hackman

About this app

Measure your reaction time to the nearest millisecond.

A novel hold-and-release system combined with trials is used.

* How to use *

To begin, press and hold your finger to the screen.
When the screen turns green, lift your finger up as fast as you can.
Complete a total of 5 trials to get a final average of your reaction time.

No lifting early! Lifting early causes your current run to be reset.

Ratings and reviews

No ads and it works great. The timing is much better than online websites. The interface is clean and intuitive. Suggest adding a beep to test auditory response time too.

I like the concept. Technically it should measure reaction times more accurately than some other methods out there. But the test screen is just too littered with unecessary texts, its too distracting. I don't think a plain screen is too much to ask for

Great app. Very addicting trying to get a faster and faster reaction time. I like that some times it's a long wait until it turns green which makes me twitchy and I let up too early or let up too late.
