Astrolabe Clock is an astronomical clock inspired by the astrolabe, an ancient astronomical instrument used to tell time and to predict the location of the Sun, stars and planets. This modern interpretation gives a view of the sky showing at a glance the time of day, day of year, and the location in the sky of the Sun, Moon, planets and stars. Astrolabe Clock also gives the time of sunrise and sunset, the phase of the Moon, transit times for the Sun, Moon, planets and stars, and can be used to show the occurrence of solar and lunar eclipses.
What's New in Version 1.11
New USER SUGGESTED features:
- Local Apparent Sidereal Time displayed
- Ecliptic Poles shown
- Option to reverse East and West directions. Use this when in the "North" projection to show time increasing clockwise as on a traditional astrolabe instrument.
- Fixed error in the location of the boundaries between zodiac signs
- Settings button now consistent with iOS 8 style
- Other minor bug fixes
As a mechanical astrolabe user
Oh look, the North Star. No, that is not the North Star. To begin with, you were looking to the south. That is Venus.
That was an actual exchange with a neighbor. With this incredible app, you too can be the neighborhood expert on those bright objects in the sky.
I have used a mechanical astrolabe for decades, but it does not show the planets. This iPhone app is the perfect complement.
Simple and effective
Been using it for years. No waiting for a heavy app to load, no looking like a weirdo pointing your phone at the sky. A 2-second glance and you know what you're looking at.
A very simple and efficient app. The chart is easily understandable, which helps me to quickly locate the brightest objects in the night sky, prior to setting up my telescope. Thumbs up!!
