4 stars: The program is good. I live in a quite lighted area, so the stars I do see are easy to find. The tracking is not perfect but it is close enough for person who just wants to stargaze and let's be honest, amaze your friends with your astronomical knowledge.
3 stars: I find that the app never aligns with the sky... even after several attempts at rotating my phone... this is 3rd phone with the same issue....
5 stars: It's a great app to have right at your fingertips. The notifications about what is happening in the sky are great and I really enjoy what I learn from them.
5 stars: My compass was off but calibrated it through Google maps. Great app!
4 stars: I don't use it as much as I'd hoped, but it's proved reliable when there have been important planetary meet ups. When I have clicked the notification its taken me right to the area in the sky and even provided an arrow direction to help you identify it. For that it's a good 4 star.
5 stars: I have been using the free version for a few months and it is very useful even though I haven't dug very deeply into using all the options. The notification are extremly helpful not to miss event. I love the guide arrows to show you where to find the event targets.
4 stars: Very neat app. Has cool graphics and non-invasive ads. Locations are accurate and it runs very well even on a budget tablet. Unfortunately I just don't use it often enough anymore, but would recommend it to anyone!
4 stars: As an amate...
