Solve problems at a good tempo like a game, and memorized problems are registered in the Hall of Fame, and new problems will appear as the number of registrations increases.

It is said that it is better to activate the brain and review at an early stage in order to establish the memory. In addition, there is an efficient time interval for reviewing from the "Ebbinghaus forgetting curve".

This app is designed with the guideline of how to memorize efficiently and easily to fix the memory. The rough design contents are as follows.

◆ All questions are random
I don't remember the order of the questions = I don't get bored = I activate my brain

◆ Re-question before forgetting even if you answer correctly
Review at first shorter and longer intervals than the forgetting curve

◆ Questions as many times as you want until you remember (quantity rather than quality)
If you make a mistake even once, you will be asked again after a while.

◆ Entered the Hall of Fame with correct answers 4 times in a row
Hall of Fame questions will not be asked after registration

When the Hall of Fame rate exceeds 70%, the next class will be released and the number of problems will increase!
Aim for all problems inducted into the Hall of Fame!
