What is the app called that tells you what stars/planets you see?

[Adollop]

I'm sure I've heard of an app where you point your phone at the sky at night and it tells you what stars or planets you can see, but I've already downloaded two and they're not showing me the actual sky I'm looking at.

Do I need the premium version, I couldn't see it mentioned? Or I'm downloading the wrong apps... one was skyarium or similar, the other maybe sky map ...

Any recommendations would be great.

It's also worth looking at spot the station which tells you when you can watch the ISS pass. I still find it exciting to see!

So .. I installed Google sky map on my old phone and it works fine, so it's just the lack of compass on my new phone that is causing the problem.

Thanks for all the recommendations.
