upgrade to premium crashed program

After upgrade to premium all controls fail to operate and stuck in one view (planetary) only. Had to uninstall and reinstall free version to get a working app. I paid for an upgrade that does not work. After re-install premium flag not set so if I want to throw my money away again and try it again I have to pay more money. NOPE! Done with this POS.

Fades Out Quickly

I select a view it but it fades out before I can enjoy it.

Can't get my location right.

I tried to install this app on my tablet and it asked if it could use my location, but it marked my location in a large city almost 100 miles away from the town I live in. I uninstalled and reinstalled it three times and it never got my location right. It seems like it should be a better star-gazing app than the one I am currently using if it could only get my location correct.

Needs a LOT of work

The UI is poor. The controls are difficult to use and often require 2 or 3 taps before they react. This is a good idea but it needs a lot of work.

Interesting app that had potential but fails to deliver. I was hoping for a more complete set of ephemeris features but this app only really provides sunrise, sunset, and length of day. The UI is pretty confusing and hard to use. My preference in SkyMap for night sky orientation and then a simple weather app for sunrise and sunset. When this app gets a real ephemeris calculation, then it'll be gold.

Doesn't work well

Seems to hang up a lot. Non-intuitive. What few functions I could get to work seemed fine, but commands and gestures weren't consistent across views.

I purchased this app about two years ago, SI I have seen many changes. This app has a lot of potential, but there are design decisions that detract from the experience. Please! Change the star shapes to something useful! Those diffraction spikes are huge and make everything difficult to read.

Fair - Implementation problems

The program itself has potential however it does not work well on my Surface Pro 3. After using it for a short period of time none of the buttons seem to work to switch between the various sections of the application. The problem is that the button "hot spots" no longer line up with their screen icons. Initially I thought this was due to the calibration of the touch screen but using the track pad on the Surface Keyboard it is apparent that they are completely off center. For instance, hovering over the Sky View brings up the dialog for the phases of the moon. It actually takes a reboot to temporarily correct the problem. This essentially renders the program unusable. Probably an easy fix... I will upgrade my rating when this is fixed. Addendum: With this final reboot of the Surface the buttons now seem to work as they should. I am experiencing random crashes when moving back and forth within the program but I have added another star as the controls seem to be working as they should.

Like user Gustavo said, there are several bugs. The hint pop up tells you to tap what looks like a refresh button to enable the point to sky feature, but it doesn't work. Tapping the telescope button over and over seems to activate the point to sky feature, but only randomly. This feature was the main reason for choosing the app. Also, the alignment of what you see in the app, and what you see in the sky with your naked eye, seem to be shifted to the left. They do not line up. If the non responsiveness and accuracy of the point to sky feature, the lower left info box that won't go away and the scrolling issues can be addressed, this will be a REALLY NICE app!
