The Eerie Beauty of the Apple Watch Solar Face, and the Anatomy of Nightfall
Wow this makes me want to buy an Apple Watch!In the military knowing first-light and last-light, down to within a few minutes, is essential daily. I have an app on my phone that tells me sunrise and sunset, but as the article describes these aren't the same thing. I also have a very expensive top-of-the-range Garmin watch and even that just tells me the less useful sunrise and sunset, which makes me suspicious it's not as military as it markets itself as.I don't know if anyone knows an app that gives first-light and last-light for the phone, so I don't have to buy a new watch?
