The Eerie Beauty of the Apple Watch Solar Face, and the Anatomy of Nightfall
Wow this makes me want to buy an Apple Watch!<p>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 <i>that</i> just tells me the less useful sunrise and sunset, which makes me suspicious it's not as military as it markets itself as.<p>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?
