5 stars: I love the tracking system. It makes satellites really easy to find. Intuitive. Nice integration with star maps. Planned trajectory is also a good detail. Priced reasonably if you're going to use it a lot. Clean, functional app. Well designed.
4 stars: Pretty neat animations and well designed notification system. A few things to enhance the app: 1) I would have liked a lot more info about each satellite (purpose, history, technology, anecdotes, etc) 2) There are only 25 satellites showing in my list, would like a more complete list 3) The link to Star Walk 2 simply opens the app, it would be nice it it went directly to the satellite I'm navigating from.
4 stars: Not possible to choose which Google account on the phone to subscribe with and the app always chooses the one with no payment attached to it. Edit: as this is a Google issue, I think it's unfair to leave a low rating considering I liked the app and would have subscribed. Rating thus adjusted.
3 stars: I installed the app and couldn't find a way of closing it - it seemed reasonable but was frustrating - I'll uninstall it.
3 stars: Needs to add many more satellites, rocket bodies, etc. The tracking is much easier than Heavens Above, but Heavens above will have a new object of some kind every minute or two, while this one may only track half a dozen all night. Also, intensities (brightness) should be listed. The bones of this app are good, but needs a lot more meat.
2 stars: Nice user interfa...
