## Astrolabe Clock Description
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.

## Astrolabe Clock Reviews in United States

### ***** "Really Neat Way to Look at the Sky!"
This may not be brand new or flashy, but I really love the way this astrolabe visualizes the relationships between the celestial bodies as a function of time.  If you actually read the instructions and play with the app you learn a lot about how things are related.  Well done!
-- PeteNH, 2025-01-25

### ****- "Perfect clock visual"
Love how app shows solar & lunar positions & elevations correctly.  The perfect fix to adjust to the idiotic standard-savings timeΔ.
Please add alarms & or ability for postings.
-- Alaskadotnet, 2024-03-14

### ***** "Slow under newer iOS versions"
I love this app and have used it for many years, it was my first astronomy app on this iPad.  Unfortunately, since iOS 13 it’s gotten much slower and laggy, hopefully the developers can update it.
-- woof1234321, 2022-08-23

### ***** "Fascinating"
What a delightful little gateway to astronomy and geometry. I find it just all kinds of fun to poke around to different times and places, maybe I’m weird. This is the only app on my phone that is both truly free and that I open regularly.
-- WiseOldDuck, 2020-08-16

### ***** "Perfect"
This is just a wonderful program, might not be as pretty as some of the others but it’s layout is crisp and clean and FREE.
One of my first goto astronomy apps everyday
-- The real GeoXXX, 2020-05-20

### **--- "Abandonware"
Extremely poor performance on latest iOS. Hasn’t been updated in over 4 years, needs to be removed from app store.
-- WhatNowHuh, 2019-12-20

### **--- "not very responsive"
Under IOS 13, I can barely zoom in or out. When I tap on a planet, it has to think about it and decide if it wants to show me information about it. The red fonts are hard on the eyes. The last update was 4 years ago, and I suspect that the latest iOS versions are causing some of these problems.
-- fwoomp, 2019-11-23

### ***** "Useful"
I am learning to use an actual functional astrolabe, and this app has been extremely useful in my studies. Simply having the known altitude of the sun at my location allows me easy comparisons to my manual readings and helps me adjust/correct my mistakes. And it’s free?! Almost too good to be true.
-- Hedgehog154838, 2019-06-02

### ***** "the perfection of simplicity"
please make sure this is compatible w ios updates!

Love This!!!

all the info in my hand!
-- Jolontru, 2018-08-28

### ***** "Perfect!"
I just got my first GermanEquatorial Mount (with a new Scope obviously), and was really disappointed when I found-out about setting the Right Ascension manual dial.

Now, with this App, I have my local position setting right on my phone....already calculated.   All I have to do is aim my scope due south, reset, then find my next target.

Thanks much!
