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.

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.

It's good reaction time test app. But however reaction time can be measured in many other ways. This is only one of them. And anyone can score under 500 ms response time. Fairly good, but other apps give you more tests which increase your focus and attention.

even an insane developer would add setting to press instead of release. you press to shoot, you click to shoot. you do not release to shoot. novel = requires retraining.

Great app, only gripe I have is the random super long 15s wait time. That's an eternity when trying to measure fractions of a second.

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
