Half-Moon "Sleep" App on Iwatch

Every night, I put my watch on the charger and every morning I wake up an I have to turn OFF the Half-Moon Sleep App that I didn't turn on! I have tried deleting this particular app's icon but then, I have to re-add it in the morning so that I can turn it off an app I didn't turn ON again. I am very frustrated!

How do you turn off something that you don't turn on? I don't want this on my watch but, it is starting to appear that I have no choice.
