KuruKonai

"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 "won't", the unhappy one will cry for you.
And you can kill time while you wait for someone.

"KuruKonai" means "will come or won't" in Japanese.
