The operation is very easy!

When you start, the "red" and "green" marks will light, so just press the left button if red and the right button if green. Repeat this 10 times, and when finished, the following information will be displayed.

・ Reaction time until the button is pressed after the mark lights up (maximum value, average value)
・ Number of button press errors

At the same time as this display, the voice will also inform you that "Your reflex nerve age is XX years. In addition, there is a mistake of pressing X times, so care is required."

As you can know your reflexes age (indication), and pressing errors may lead to "acceleration and braking missteps", please use them as a reference to prevent future accidents.

※ Because this application's execution result is just a guide, please use at your own risk.
