Lots of quirks. Can't get the phone app to display all my watches in different tabs like the screenshots show. It only shows 1 watch, & it's the wrong watch more often than not. Sometimes I wait hours for it to show the correct watch. Battery graph scale not showing all 100% is frustrating. Lots of overlapping text in UI. Also, the persistent watch notification always triggers the "new unread notification watchface icon" making it useless. Not enough characters to review thoroughly. Still 5⭐

it's the only app that provided what I needed (chart of battery over time), but the constant notification on watch and ads with sounds (sounds!) are the reason of -2 stars
