There’s nothing better than a quiet night of stargazing. Well, nothing, except knowing which stars and constellations you’re seeing. These apps can help you pinpoint exactly which celestial objects you’re seeing, but they’re not all created equal; we’ve rounded up our absolute favorites.

This app provides a visual representation of the sky. All you have to do is point your device in the direction you want to learn more about in the sky. Since StarTracker doesn’t use your camera, you can point it in any direction or at any object for a clear view of what the sky in that direction contains.

You can also view a list of sunrise and sunset or moonrise and moonset times and receive related notifications. In addition, you can easily change your location to anywhere in the world to get a view of what the sky looks like in another country.

SkyView Lite is an easy to use app that allows you to point your camera at the sky and see what constellations and planets are there (whether you can see them or not). A handy way to do this is to point down to see what stars are visible on the other side of the world (you might even find a satellite here and there).
