### 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!

### 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.

### 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.
