Reaction Test Pro

By Freedom Apps

This app is only available on the App Store for iOS devices.


Welcome to the simplest Reaction Test App available on the App Store! Measure your reaction times and compete with your friends and others around the world!

Reaction Test Pro has only two buttons - "Start" and "Stop". It couldn't be any simpler:

- To start a reaction test, tap "Start" - the indicator lights at the top will change to orange to show the game is in progress.
- As soon as the lights turn green, hit "Stop" as quickly as you can!
- Your reaction time is then shown.

Your reaction time is measured as the time taken between the lights changing to green and you tapping stop.

The application is compatible with the iPhone, iPad, and iPod touch running iOS 8.0 or above. User accepts all liability for use of this app.

What's New in Version 4.0

We have now passed 500,000 users! To celebrate, here's an update containing:
- an improved interface for all iOS screen sizes
- improved quality graphics
Enjoy, and keep those reaction speeds up!

Customer Reviews

Great for fast paced games

This app is pretty great for games like csgo I like it because you are looking at one point and if an opponent is far away this test will help you react to a small movement

Horrible reaction test

The entire screen should light up when it changes, not just the top part. Plenty of discouraging comments when you get a mediocre score. Also, the start and stop button should be the same button.


This app is horrible, for one why are there two different buttons, also why is only a sliver of the screen changing color? Needs work
