So far, so Good

After the old Dark Skies app which i’ve been using for the past 10 years no longer worked with the newer iOS, i’ve been searching for a decent replacement. Not wanting to spend any money on trash, i’ve been downloading countless “free” apps, but none concisely provided the basic functions that i wanted : sunrise & set and moonrise & set, as well as moon phases, for anywhere, anytime. So i finally splurged and spent 99¢ on this GPSAstro app and am finally a happy camper once again !

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!

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.
