Why it is on this list:
Top free educational app on Google play
Deffinitely worth downloading, it gives a full 360° 3D realtime view of
the whole skymap, showing every object's current, changing all the time.
It also gives a full 3D globe of all the planets in the solar system,
showing the current light and dark sides of the Earth, but what I really
like is that you can change the light spectrum, giving different views
such as visable light and x-ray. Deffinitely worth it.
