### 5/5 — Useful for finding your stellar bearings

*2022-01-27*

This app helps me to find at a glance both planetary bodies and the names of visible stars in my area. It works very well to help me get my bearings. My vision isn’t as good as it once was and having this tool makes it enjoyable to view the stars and planets, many like Mars, Jupiter, Saturn, and Venus can be seen with the naked eye.

### 5/5 — Useful, practical Astronomy app.

*2020-12-08, version 1.9.17*

Great app for quick location of objects. Easy to use and well designed.

### 5/5 — Great App

*2020-11-14, version 1.9.17*

Good quality, great for learning about constellations and zodiac signs. Overall great app! 😁

### 1/5 — Compass spins around - no support

*2020-10-11, version 1.9.17*

The compass doesn’t point in the right direction. There is no way to contact the developer. Total waste of money.

### 5/5 — Me

*2020-10-06, version 1.9.17*

Super cool!!

### 5/5 — Love it, but...

*2020-09-06, version 1.9.17*

This is a great app. I absolutely love it. My only complaint is that sometimes it’s not calibrated right. I’ll be pointing south and the app is saying say West. And I try to recalibrate it. Other then that it’s great.

### 5/5 — ممتاز

*2020-07-10, version 1.9.17*

ممتاز

### 5/5 — Great app!

*2020-06-09, version 1.9.17*

It’s very accurate and is perfect to help me spot stars and planets, it showed me the best time to see Saturn and I will see it for the first time because of this app :)

### 5/5 — The best star tracking app out there

*2020-04-11, version 1.9.17*

I love this app because it doesn’t need an internet connection to work. It uses your phones compass and downloaded content to show the stars and constellations. I use this app a lot when I go back country back packing.

### 1/5 — Disappointed

*2020-04-09, version 1.9.17*

Used to work flawlessly. Uninstalled and reinstalled several times but every time I open the app graphics just spin around aimlessly.  Moving on.
