Comments on Mobile Observatory Free for Android

★★★★★ Julie Jackson · Oct 11, 2022

This app is amazing!!! It allows you to zoom in and tap on even the smallest and farthest of stars, to tell you their name and other information about them. It even has a mode where you can point your camera at the sky, so you can get info on stars that you see around you. Super awesome. Best star app!!!

★★★★★ Janene Hamilton · Nov 2, 2022

Great easy functionality and excellent information for novice or experienced astronomy fan

★☆☆☆☆ Susan Mosser · Oct 20, 2022

Wouldn't show me anything it just kept asking me to join for a paid monthly premium subscription in order for me to access anything that was showing on the screen. Totally disappointed

★☆☆☆☆ Deane Vincent · Sep 8, 2021

Awful, all I wanted to do was find out what the bright star was in the sky right now. I am happy to set up everything and look properly at the app at a later date but as a quick application of reference it was more than useless. I will now be uninstalling this user unfriendly app.

Junk! When you enter your location it gives you a pop-up asking for it again! If you try to click off the pop-up wanting your location it sends you to the location select menu anyway!

★☆☆☆☆ Tim Cleary · Aug 29, 2021

Thinks my location in Sydney, as set by GPS, is on a mountain somewhere. Maybe the sun is in the right place but nothing else is.
