Not Rocket Surgeons

This app is pretty ok, though I personally find the interface a bit awkward and confusing (probably because I do not use it that much). What really outrages me is the utter incompetence of the app's managers. Notifications of events pop up from time to time, also urging me to buy the app, and every now and then the events are wildly wrong. A while ago, it was "Mercury at Perigee", I mean, come on, if you are going to use big words, at least know what they mean. Then I just saw "Pluto at Aphelion", which I think they later modified to "Opposition", but seriously, what is going on here? My math would indicate that Pluto is not due for aphelion before at least 2101, how do competent people make that mistake? And how can you trust the accuracy of their app if their basic astronomical sense is so questionable?

Poor sky-viewing app.

There are so many areas for improvement with this app it is not possible to list them all, and I do not suggest you use it nor upgrade to their premium product; I have not upgraded and have no plans to. I suggest you try Pocket Universe instead.

For starters, the interface is clunky and unwieldly. Function icons are not clearly labeled, and occupy valuable display space on my phone. I should be able to hide these icons to make full use of my phone's display or they should auto-hide themselves in some off-screen fashion. To continue, pop-up information does not clear itself and gets in the way of the skyview display. The app continued to display data about Mars when I had navigated away from that planet's view in the "orbital" view. The app also does not remove information that is no longer relevant to the star/planet/satellite object that I am no longer looking at through the app. There is no obvious control that actually removes these info pop-ups; the control only resizes the pop-ups but does not remove them. Additionally, the stars all have "lens-flare" or "starburst" effects that won't turn off. A control needs to be plainly and obviously named that can disable this effect. Finally, the "night vision" mode should be just that: everything should be low-HSV color or red. When this option is turned on, the app does not use an appropriate color scheme.

The list goes on, but these are some of the most obvious items that can be improved upon.

Very Useful, But...

This app has beautiful 3D graphics and I love the accelerometer support on the sky view. I've been using this app for quite some time and just recently upgraded to the Premium version. The calendar and the notifications let me know when something cool is worth watching and I love how I can have astronomy software in my pocket. I have recently noticed a problem, though. When I use the search feature, tap the search bar, and scroll past the "Stars" section and into the "Satellite" section, the app would hang for about a half second and then crash. In case you are wondering, the crash happened on iOS 6.1.4 on an iPhone 5 16GB. For me, this is just a minor nuisance as I generally use this app for planets and stars, but I would like to see this fixed to make this app even better. Otherwise, this is a great app and I appreciate the work put into it so far.
