### 5/5 — Simple

*2022-06-16*

Simple to use. Clear to read. Only 99 cents. 👍 Good for planning my fishing outings. 🎣

### 5/5 — Convenient and easy to use.

*2020-04-12*

Reliable , accurate, stable app.

### 5/5 — So far, so Good

*2019-10-21*

After the old Dark Skies app which i’ve been using for the past 10 years no longer worked with the newer iOS, i’ve been searching for a decent replacement.   Not wanting to spend any money on trash, i’ve been downloading countless “free” apps, but none concisely provided the basic functions that i wanted : sunrise & set and moonrise & set, as well as moon phases, for anywhere, anytime.  So i finally splurged and spent 99¢ on this GPSAstro app and am finally a happy camper once again !

### 1/5 — Moon times are wrong

*2018-10-11*

Off by about an hour, as compared to all other moon rise/set apps I have. I have location and time set properly. Sunrise/set times are correct. Not sure why moon is always off.

**Developer response:** Thank you for your Feedback.
We would like to solve this problem of yours, since this is not a normal behaviour of our app. Please write us an e-mail at appsupport@esirion.com with more information about your situation.

### 4/5 — Simple & info-packed

*2017-10-06*

Very handy and simple app for seeing civil/ nautical/ astronomical twilight at a glance, as well as moon phases and set/rise times. I always refer to this app when I'm trying to figure out how quickly it'll get dark!

### 5/5 — Fun App

*2016-12-30*

It's nice to see sunrise and sunset, but even more useful are the civil twilight times.

### 1/5 — Language

*2016-09-15, version 3.0*

Cant change language from german to english. cant change location in iOS 10 with iphone 5s

### 1/5 — Privacy nightmare

*2014-10-27, version 3.0*

Needs location access even when the app isn't running... Not on my phone.

### 1/5 — Language

*2014-10-07, version 3.0*

I have not been able to change the app's language. Too bad.

### 5/5 — Awesome

*2013-12-03, version 3.0*

Really useful i love it
