Object Information: It’s one thing to see asteroids or planets in the app.They should also be able to track and show you their movements in real time. They should be connected to large databases that can show you at least a few hundred thousand stars, nebulae, galaxies, artificial satellites, and other deep sky objects.

Robust, Accurate Charts: With the exception of apps designed for kids, the best astronomy apps show more than the basic contents of our solar system.

And for advanced users, important information needs to be available at a glance so you can spend your time staring at the stars and not at your phone. It can be confusing (or downright overwhelming) for beginners at first until they learn how to parse it, so it’s important that these apps be intuitive, well-organized, and able to provide assistance or helpful descriptions when needed.

Easy to Use: Astronomy is fascinating but there is a lot of information involved.

Here are a few other things you should make sure your app has, and why they’re important. All of the apps featured here show you constellations, yes, but it’s how they show them to you and how they make it useful (by giving a basic explanation to beginners or by providing exact coordinates that advanced users can input into their telescope, for example) that counts.

There are a variety of astronomy apps out there, and each kinda does its own thing. Best Premium Astronomy App: Stellarium Mobile Plus
