My name is Mac, and I have built this app as a quick way to test reaction times for my eighth grade science fair project. The game is split into three different types of tests:

1. A circle changes colors and you must tap it as soon as it does;
2. Tap as many red circles within a grid of white circles as you can within 30 seconds;
3. Tap a red circle as many times as you can within 30 seconds.

The whole test takes about 2 minutes, and the app supports multiple users using the same device, so help me out and have everyone in the family create a profile and try a couple rounds!

When you create a profile, you have the option of registering an email. It would help me a lot if you could leave your email so that I can send you a quick survey. Your email won't be used for anything else.
