General Comments – This app is perfect for anyone trying to learn more about the sky and what surrounds the Earth. I love the zoom feature where i am able to see certain sky objects in much more detail such as the moon. Also, I really liked how you can select a sky object by tapping on it and it will give you a wide range of information about that object. It doesn't matter whether its a star, nebula, cluster, or galaxy, Stellarium has it all.

Evaluate it - give marks for:

Ease of use- 4.0 stars: The functions on the screen are very friendly to use. This is my first use of any astronomy app and I had no problems using it. The only thing I must say is that I had trouble getting certain main star names out of constellations.

Content accuracy- 4.5 stars: For the most part it is very accurate but there was the occasional difficulty of navigating to find constellations on my android device.

Cost (Value)- 5 stars: No one likes to pay for things and this app gives you that choice. Personally I own the free android mobile version from Google Play. The only version I hear from others that still costs $2.99 is for IOS.

Relevancy to astronomy- 5 stars: Direct correlation with the subject. Almost any sky object in our neighborhood can be found and researched with this app.

Interest- 5 stars: I have always been interested in the contents of outer space. Stellarium helped feed my interest more in the field of astronomy. I have learned about planets and stars alike. Thank you Stellarium.
