“SkyORB is fantastic for anyone interested in the night skies, but it’s not just a star-gazer’s handbook.“

"This is another fascinating app."

"We love SkyORB because it not only offers 3D images of the planets and the stars in the sky, along with comets and asteroids, but it also comes a 'point to sky' feature that allows you to aim your handset towards a star or planet and it'll identify it for you"
- PC Advisor

Customer Reviews

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.

Lots of bugs!

Maybe when this app will work flawlessly it will be a nice one. At the present (ver 3.3.3) it looks a lot a beta version! Some button is not active(?), some function doesn't do what it is supposed to do. The menu/submenu are not intuitive, you just keep tapping to know what is active and what is not, as on the screen nothing happens. Option activation is sometimes slow, sometimes it stacks in a mode and you have to reopen.... It's subpar, it needs a lot of work to become acceptable. The Premium version is even more disappointing. I rated 2 stars for the potential, hoping they will fix it.

A bit different approach but good

You need to learn their organization but it has a lot of good features.
