Okay, so I don't need to know the wind speed and really don't care if the moon or Sun will come up or not. Everything including temperature, humidity, it's very easy to tell what your battery level is in the phone and on the watch. I was a bit disappointed when clouds showed up on my watch but it was a clear sky. Somehow that changed and now it's correct. It does suck up some battery, Outstanding! Ok one small con. Uses 9% battery while idle. I have to charge daily instead of every two days
