It is a simple application which can check the present intuition.
Intuition is checked during morning attending school and commuting at free little time, such as time for recess, -- lets sharpen well gradually.
When intuition is not improved easily, it must surely be clear by heightening concentration.
Since it is a free application which can be enjoyed easily, please enjoy those interested.
In addition, this application can enjoy two games, "Intuition" and "Concentration."
