Simple & info-packed

Very handy and simple app for seeing civil/ nautical/ astronomical twilight at a glance, as well as moon phases and set/rise times. I always refer to this app when I'm trying to figure out how quickly it'll get dark!

Moon times are wrong

Off by about an hour, as compared to all other moon rise/set apps I have. I have location and time set properly. Sunrise/set times are correct. Not sure why moon is always off.

Extremely useful app

Dig this app. Sunrise & sunset is always extremely helpful; especially when you have dogs and all parks/greenways/trails close at dusk. The phases and rise/set of the moon is also neat to have if your a nighttime sky gazer. No extra bs, just clean and simple. Perfect.
