The main purpose of this application is to provide a tool to test your ability to concentrate at varying times of the day. You may be a morning person or an evening person. Find out for sure. Then, when you are under pressure to learn or study or just be at your finest, you will know when to give it your best shot.
Return to test yourself at different times of the day and night. Record your results and view the graph. Your records remain on file for one month in order to provide an accurate display of when you concentrate best.
Or, you can just play games, have contests, have fun.
Simply type the numbers you see displayed and press the [Enter] key.
