We support your happy life.
If you were asked "Are you happy?" would you say yes or no?

Tap the screen of the app, and a message will appear asking the question. Depending on your answer, the Yes or No will gradually grow. You can also toggle the growth speed with a long tap.

There are two effective rules that you should follow.
1. only once a day in principle.
2. look at it a little before you go to bed.

Every day, ask yourself a question and answer it honestly. And just look at it.

This app was inspired by a memory of a book I read once upon a time.
--
In your bedroom, prepare two transparent jars and a black and white Go stone.
Every day before bedtime, on days when I have done something good, I put only one white stone in the jar.
On days when you did not, put the black stone into the other jar.
After a while, the jar of white stones will surely be filled.

I hope your Yes grows. We hope you enjoy it for many years to come.
