### 5/5 — Perfect!

*2017-11-05, version 1.11*

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!

### 5/5 — Perfect

*2017-09-28, version 1.11*

This is literally exactly what I wanted. I had a Win-32 application that did some of what this thing does as my background, but this is way better. Most importantly, it's in my pocket. 

Love the drag-the-time feature. Clear that the author wanted to make the app usable above all else. Works on >= iOS 6 which is perfect for a Luddite like me. No dumb or useless features. All parameters manually settable.

Perfect.

### 5/5 — As a mechanical astrolabe user

*2017-07-20, version 1.11*

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.

### 5/5 — Clean and simple

*2016-07-10, version 1.11*

Great app!

### 5/5 — So cool !!

*2016-03-29, version 1.11*

The mini skyline right in my hand ! So intuitive with great menus and settings !! 

So awesomely simple and functional. 

Would be nice to set an alarm for upcoming sidereal time, and full moon alerts. 

Great App man !

### 5/5 — Simple and effective

*2015-12-25, version 1.11*

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.

### 5/5 — Excellent!

*2015-10-19, version 1.11*

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!!

### 5/5 — Astrolabe

*2015-07-14, version 1.11*

Very clever, useful, and free to boot. Well done, Sir.

### 5/5 — 🚾

*2015-06-22, version 1.11*

Way cool.

### 5/5 — The best Astrolabe since the ancient brass ones!

*2015-06-02, version 1.11*

If you want to see how the sky above us works, where things are, and when eclipses will happen, this app shows you. Faithfully reproducing the ancient Astrolabe it shows you the heavens in a way that makes everything make sense. Get this and enjoy the sky with a new understanding! 

I have had several versions of this wonderful program and this newest version gives you many excellent features. This is one well thought out and executed app!

### 5/5 — Magnificent

*2014-12-15, version 1.10*

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!

### 5/5 — Superb implementation

*2014-11-12, version 1.9*

October 2014 update:
A great App just got even better ... Thank You.
__________

This is interesting, accurate, and educational.
... and it displays beautifully on the iPad.
The Author gave a very helpful reply to my question regarding the small offset of the Time Ring: [i.e. it shows the Equation of Time].
I would highly recommend this App to anyone with an interest in Astronomy and/or Horology.

### 5/5 — Astrolabe

*2014-10-16, version 1.8*

I love this app. It has so much useful info. However, since the recent update, it won't work on my old iPod (iOS 6.1). Please fix if possible. It would be great to have it back.

## Most critical reviews (10 lowest-rated)

### 1/5 — Not very good

*2012-09-23, version 1.6*

The date and time settings don't stay current. They always revert back to December 31, 1969 at 18:00.

### 2/5 — Abandonware

*2019-12-20, version 1.11*

Extremely poor performance on latest iOS. Hasn’t been updated in over 4 years, needs to be removed from app store.

### 2/5 — not very responsive

*2019-11-23, version 1.11*

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.

### 3/5 — Update fail

*2014-10-16, version 1.8*

Came up with update but store says no longer available.. How do I update it?

### 3/5 — Astrolabe clock

*2012-09-25, version 1.6*

Nice app but date reset when one enters settings is a bad bug. Must terminate app to get time to go current.  Can't set to any other date or time.

### 4/5 — Beautiful app

*2026-04-30, version 2.0.1*

Beautiful app but widget is not working?

### 4/5 — Perfect clock visual

*2024-03-14, version 1.11*

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.

### 4/5 — Pretty Good

*2015-09-14, version 1.11*

I like this and it works well. It shows a lot of useful astronomical information "at a glance".

### 4/5 — Almost 5 Stars

*2014-10-26, version 1.9*

Does just about everything I want...except show age of moon in days. Otherwise great app.!

### 4/5 — Simple Sweet!

*2013-01-02, version 1.7*

For the amount of detail and useful information I would rate this app fairly high. Better than many $ apps on astronomy.

### 5/5 — Great app

*2026-05-01, version 2.0.2*

Simple, useful features, and responsive developer.

### 5/5 — It’s amazing

*2026-04-24, version 2.0*

This app is truly brilliant at what it does

### 5/5 — Really Neat Way to Look at the Sky!

*2025-01-25, version 1.11*

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!

### 5/5 — Superb!

*2022-11-01, version 1.11*

I purchased this app many years ago, and I use it frequently. It is a wonderful clear, but detailed, display of the sun, moon and planets.

### 5/5 — Slow under newer iOS versions

*2022-08-23, version 1.11*

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.

### 5/5 — Fascinating

*2020-08-16, version 1.11*

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.

### 5/5 — Perfect

*2020-05-20, version 1.11*

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

### 5/5 — Great Astronomical App

*2020-01-22, version 1.11*

Although there are many more complex astronomical apps now available, I still after nearly ten years, use this Astrolabe as it provides a simple quick view of the night sky.

### 5/5 — Useful

*2019-06-02, version 1.11*

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.

### 5/5 — the perfection of simplicity

*2018-08-28, version 1.11*

please make sure this is compatible w ios updates!

Love This!!!

all the info in my hand!
