## Simple Reaction Time Test Description
This app is a very simple way to test your reaction time. When you tap play, the app changes back and forth from red and yellow screens. It then changes to a green screen with a millisecond timer, and you have to tap as fast as possible to get your best possible reaction time. 

You can compete with friends by sharing your fastest times via iMessage, Twitter, Facebook, etc. 

There are also In-App Purchases to reset your average time and remove in game ads.

## Simple Reaction Time Test Reviews in United States

### ***-- "Decent"
I’m reading the little amount of reviews and they don’t seem to mention anything about getting a really low reaction time but I have a suspicion something may be up since I can get a reaction time of zero averaging 100-300 without trying, anyways ignoring the fact I can get 0 30% of the time; with the stuff and the way it works I will rate it 3 stars because of the turning yellow making it hard to keep up along with the fact my thumb cannot keep up with my brain most of the time making my average 100-300.

### ***-- "Good game but annoying"
My question is why do they put the yellow that’s just annoying because I’m just trying to get a consistent time
-- Blu Bull, 2020-07-20

### ***-- "Good but inaccurate"
The app is simple and works fine, but the results are inaccurate simply because of the touchscreen aspect of it. An easy fix would be to make it so you touch the screen to start the timer and then stop it by lifting your finger.
-- ssquare_, 2020-02-18

### **--- "Ads"
There are soooo many ads. Other than that it’s good.
-- Farenhyte, 2019-08-03

### ***** "Simple but addictive"
For the past 22 hours I have been transitioning between a red and green screen non stop. Currently my girlfriend is very upset with me and a blister is beginning to form on my right thumb. Stuck trying to beat my top score, yet all I can manage to mustard up is 405 milliseconds. This app is more addictive than the over the counter blue Advil from Walgreens. Awesome app, definitely worth a download!!
