5 stars: Of all (4) star apps I have tested, find this one operates as described, is very easy to use and is accurate. The graphics are clear easy to read and uncluttered. Just enough options to customize without being overwhelming or pointless. Because of this I am considering upgrading to the next level. Definately best of the star apps for smart phone use.
5 stars: Absolutely love this app. It's perfect for star gazing or just seeing what planets you can see. You don't need the upgraded version to use the app, but you get way more high definition photos. The only thing is it no longer shows the pictures overlaying the Constellations even when that option is checked to work.
2 stars: It's kinda unreliable. When I point my phone to the north it thinks I'm pointing to the southwest. When I aim my phone to one point the content keeps moving. It has no idea where the poles are. This is only a problem with this app. Never problems with other gps or apps that use my location
