The sky colors are very realistic, much more than in Skysafari. The day sky color is a kind of pale greenish-blue. The Moon is displayed very dark gray and way too large (the Sun as well) even when Moon magnification factor is set to 1 (one). Skysafari displays Mercury, Mars and Saturn as an unrealistic fully saturated orange, red or yellow and the Sun is also displayed hard yellow. + Several 'skies' can be saved with each with its own settings

+ More objects in catalog, both solar system and deepsky / stars * enabling and disabling constellation figures, labels, star labels, horizontal or equatorial coordinates

* Can be used as a star chart while observing. * Nice horizon panoramas, including own made. * extensive object database, nice star charts and rendering, are very fast and responsive even on my not-so-new devices (Macbook Pro 2011 for Stellarium, Sony Xperia Z Ultra (2013) and iPad Air 2 (2012 ?) for Skysafari ). Tested: Stellarium 0.15.1 on macOS El Capitan vs SkySafari Pro 5.0.1.0 on Android 4.4.4 (and iOS 9.3, behaves the same).
