2x free [and] ad-free astronomy apps

[RT65CB-SWL]

Just downloaded 2x free Android OS apps to my Asus Nexus 7 tablet and a SIM free Samsung S6 'phone, (used as a pocket tablet). 

1. Sky Wheel. Basically it shows a view of the planets as viewed from Earth, (inc. Moon and Sun), in the sky without a starry background. Needs a wi-fi connection or smartphone/tablet with SIM/internet access to get an approximate fix to your location for the RA & Dec or longitude & latitude of the solar system bodies.
2. Mars Sky.  As above... shows Earth, Moon, Sun, etc., inc. Phobos & Deimos from twelve Martian locations and the option change the calendar to 'Darian' or 'Mars Simplified' in settings. 

Both apps are small, (<6 MB each), ad-free, simple to use, (therefore a nice small introduction to astronomy apps for beginners), and released by xeronaut.com via Google Play.
