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.
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
Ratings and Reviews
I like this and it works well. It shows a lot of useful astronomical information "at a glance".
Wow! I love looking at the brass astrolabes in the Museum of Science in Oxford. Now I have the C21 equivalent on my iPhone. And it works. Found by accident looking for a calendar of moon phases (and rising times). This does that and heaps more - identifies stars, shows the planetary positions. Unlike the brass astrolabes, this can be easily configured for any latitude. A beautiful app that's really practical. Top marks!
I love this app which shows the position of the sun, moon and planets compared to the earth along with length of day at any time of year. Very nice looking and very usable.
