Mobile Observatory – App Review

I have sat down to write an app review again after almost a year. I usually write reviews of science and education apps. In today's episode of the app review series I will introduce you to an astronomy app. For lovers of astronomy this is a wonderful app. Let's take a detailed look 😀

What makes it special

Many people would like to observe the sky and perhaps never get the chance, because it takes a lot of kit. With this app there is no such worry. You are bound to be surprised when you hear what it can do.

Suppose you have a wish to watch a lunar eclipse, or you want to see a comet. How would you get the news? No need to worry — this app will tell you. You can also find out when Jupiter will come into alignment with the Moon. Some of the main things you can learn:

* A live map of the sky * Detailed information on stars * Detailed information on planets * Various deep-sky objects * Meteor showers * Detailed information on asteroids * Solar eclipses * Lunar eclipses * Detailed information on comets * Remarkable views of the solar system And a great deal more.

Now let's go through all the features.
