User reviews

Night Sky app

Found this the other day and checked it out. It does not take a lot of memory on the iphone, decent graphics but slightly different user interface that is currently hard on senior eyes. I was able to run the night sky backward just over 2000 years ago, very nice. I was not able to figure out how to change my viewing location if I wanted to see the night at a different location. This version had no ads which is also nice. It has earth and 7 planets, 88 constellations and a handful of NGC’s along with night vision. If the GUI was easier to see I’d increase my rating.
