Toreapuri train the brain is a simple memory.
Just remember to answer the question several times the numbers will be displayed.
Number of digits, the number of display, display interval can be set to your liking.
※Value can be set
数字桁数：1桁－7桁(Number of digits)
I think more than 20 the number of display digits, and a great memory if you can correct the problem.

There are also other apps.
