"KuruKonai" is the Apple Watch stand alone App.
It tells you the person you wait will come or not.
Of course, it is tiny entertainment. Not serious.
Please turn the Digital-crown up and down.
If result was "come", the happy short animation will appear.
In a case of "wont", the unhappy one will cry for you.
And you can kill time while you wait for someone.
"KuruKonai" means "will come or wont" in Japanese.
