My favorite app of this type

I am a very casual dabbler when it comes to astronomy - I don't even own a telescope. However, I do like to be able to look up the occasional unusually bright object visible to the naked eye even in city lights. I most recently enjoyed the near conjunction of Venus and Jupiter in the morning sky. Venus I figured out based on past knowledge but I would never have known I was also seeing Jupiter without the help of this app.

I have downloaded and tried a number of similar apps but for my purposes this one is by far my favorite and my go-to and the only one I found worthy of taking the time to leave a review. It doesn't keep me stuck for 15 seconds on a splash screen before opening, and I don't have to have music interrupting my podcasts if I don't want it (both big pet peeves of mine with some of the competitive apps). But most important of all is the great flexibility - the user has the choice, through the settings, of whether or not to see such things as zodiac names or constellation outlines.

What else can I say other than if you are going to have one stargazing app this is the one to get.

The best star tracking app out there

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.

Interesting app

Very pleased with stargazer. Easy to use but wish it would give a brief description of stars: size, mass, age, distance, composition and iron level. All in relation to our sun.
