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.
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!
Ratings and Reviews
Everything I was expecting.
Works really well. I love being able to compete.
Had to delete this app because unable to distinguish the start stop colours.
Seems deceptively simple, but works really well.
Challenge friends and check leaderboards and achievements.
