Dynamic Visual Acuity Training

This is a game that trains your dynamic vision by reading three numbers that change quickly while moving from left to right on the screen.
Please use it for training and improving the ability of professional athletes, athletes and martial arts players.
It can also be used to increase the reaction speed of people who enjoy esports, such as professional gamers.
Or just use it as a game to pastime.

You can customize the movement speed, color, size, background color, etc. of the numbers to your liking.
In particular, the difficulty level changes considerably depending on the color of the numbers, so if it's too difficult to read or if you want to challenge yourself, try changing it.
Depending on the model, it may be easier when the number movement speed is 4 or 5 than when it is 3.

Depending on the model and OS version, only two or one of the three numbers may be displayed.
In that case, it may be improved by changing the moving speed of the numbers or changing the vertical or horizontal holding of the smartphone.
