Carpe Noctem Nokia is a great application of augmented reality with which we can know the name and the exact position of the constellations, stars and planets simply pointing your device towards the sky. It has a database of over 9000 stars, 88 constellations and all solar system objects visible to the naked eye. Definitely an application to enjoy and learn at the same time. Perhaps worse is the ad annoying, but that is an easy fix.
Carpe Noctem Nokia Changelog for v1.1.1:
Fixed bug that did not display the planets, the Moon and the Sun
