Comments on Star Tracker - Mobile Sky Map for Android
★★★★★KEL Letvinchuck· May 21, 2026
Simple to use... I can show people constellations and planets so easily. Love the astrological images superimposed on the constellations. Has made better sense of the heavens for me. I'm enjoying the updates when celestial events are emailed and then area or stars and planets are highlighted in the app.

I've really gotten into looking at the stars and identifying constellations in the last few years. One of my dogs came from a very abusive situation and the whole first 1.5 years he'd hide and "freeze" outside and often take several hours to build the courage to come back inside. I never left him alone outside, so I spent many nights out there with him with nothing else to do than look at the stars. This app makes it easy to identify and learn what I'm looking at. I use it fairly often.

Haven't been able to open this app for several months on Pixel 10 Pro, keeps crashing. Have tried restarting phone and reinstalling app with no luck. Please fix, this was the best app for stargazing I had found.
★★☆☆☆John Jeffries· May 25, 2026
My compass seems to be completely opposite of what is truly the correct direction. North is South and South is North. How do Incorrect?
★☆☆☆☆Mike S Smith· Jun 9, 2026
App has become unusable. My location is always out by at least 300 miles, and it doesn't even know north and south. I could be stood still, but still the compass keeps moving every couple of seconds. Totally useless.
