This one is called LCD Black . $1.29 on the Play Store .
This is one of those they threw everything at the watch and kept all the good stuff that stuck.
7 user settable complications , moon phase , watch battery left , heart rate , steps , mileage walked , week number , day number , date , time (of course ) , lots of color , background , index , "5th Setting " , and AOD options . Many of the built in options open apps with a touch . Example touch the heart rate to open your heart rate checker or measure your pulse .
The 5th setting is my favorite new thing as I have it set so it's a second hand but it runs along the outer bezel and actually looks like it's under the outer shell of the bezel and reflecting onto the very edge of the screen . I'm long time married with adult kids so I'm easily amused and pleased .
I tried installing it on my GW6 and it won't let me change the complications , just keeps force closing and acting like I saved it with none selected . Seems it's either Wear 5 specific or 7 Ultra specific .
Oh , also if seems almost every developer that puts faces on the Play Store adds a "leading zero" to the hour so that they don't have to code it rearrange when it's 10 ,11 ,12 . This developer took a slightly different route which puts it more like watches from the 1980s in that the 0 is a shadow like screen burn on an old LCD watch . I really like that but would like it better if they took the extra effort to make no leading zero anoption or not at all .
