Improve your concentration and reaction speed with this simple but effective exercise. Concentrate! offers your brain a real workout by forcing it to resist its impulses.

The name of a color is displayed on the screen. Focus and decide if the name matches the font color.
For example, if the word “BLACK” is displayed with YELLOW letters, select “WRONG”. But if the word “BLUE” shows up in a BLUE color, be sure to mark it “RIGHT”.

To complete the test, answer 100 questions with no mistakes, as fast as you can.

The recorded time is a measure of your concentration skill and reaction speed. See where you stand by comparing your result with the ones on the Game Center Leaderboards.

Simple, functional. Recommend.

This app is simple, clean, and functional. It does what it was advertised to do. Maybe if there were some variations or more options it could be better; regardless, I recommend this app.
