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

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.

Awesome app, does exactly what it says. The only thing that would make it better is having averages of other players, or maybe even a leader board or something like that. Still fun fun to play against friends though. 5 stars

This is a very simple tool, which is exactly what I wanted. Not an ad in sight- even better! The only problem is that I had a specific reason for needing this tool and there are no guidelines to tell you what is average, above average, etc. So, I didn't actually learn anything.
