Reaction Time Recorder

Have you ever wondered how good your reaction time is? Test your friends and family and see who reacts the fastest to red, yellow, and green light. 

- Download the app on 2 iPhones or iPads and connect when on the same Wi-Fi network. 
- Place on device 7 or 10 feet away and standing up so that you can see it
- Use the other device to "react" when a color appears on the display device. 
- Have other people try it and compare and share the results!
