With smartphones being as smart as they are now, all you need are apps that will transform your phone into a mobile observatory. Here is our rundown of the 10 best astronomy apps for Android.

1. Sky Safari

Sky Safari will not just help you become a better-equipped astronomy fan, but also just lay down, relax, and look at the stars, with features like the soothing background music, for example.

It is equipped with a powerful search, which can help you instantly find any celestial object you’re looking for. There’s also a dedicated events section, as well as a live view of the sky that moves as you move your phone, according to your location and compass.

In-app purchases are available to unlock more features, like additional objects and perspectives.

    Surely you jest!
    Using these apps to do astronomy is like playing Madden NFL and saying you've been to a football game. Or playing Call of Duty and saying you've been in combat. Using these apps is like looking at the sky through a key hole. These apps are nothing more than space games.

    If you don't include Mobile Observatory, you don't have a complete list. There is nothing else that comes close to it's power. No serious amateur astronomer should be without it.

      "No serious amateur astronomer should be without it."
      No serious amateur astronomer would touch any of these apps with a ten foot pole. Even dilettantes would shy away from them.

    Good apps, but the American Almanac 2 has way more data, including weather and calendars, and it's presented in a really unique format.

    Which of these Apps will show the International Space Station?
    You can see when it'll be visible in your area from the NASA 'Spot the Station' web page and I've seen it cross the sky three times recently.

    I told a friend that the ISS was going to be visible later that evening. He pointed his iPhone about 30ยบ down, towards the floor, and said that it's down there now.

    Major problem that you should have Highlighted Justin. This app does not work if your phone or tablet is not equipped with a digital Compass. (some phones aren't).

    Luckily, I tried it out within the two hour Google Play period and got a refund, but you seriously need to mention this.
