Quirky, odd behavior, forgets location, location services broken

Lots of good things, but major irritants.

It knows our location, but prompts to turn on Location Services.

We do, and even quit and relaunch app, and it still prompts us for LS!

Then, it resets the LS button too, turning it off!

In other words, it has become non-functional.

Past issues:

1. Whenever one brings up a pass, the start direction shows North!

2. Weirdly, half the screen on an iPad shows a list of Not Visible passes! Not sure what that's for, but you can't turn it off and it's a waste of screen real estate.

3. Sending away a pass window requires tapping an X in the corner-- it ought to go away when one taps anywhere.

4. The recalibrate compass (the biz where one has to rotate the I-device slowly in a circle tilting it) keeps coming up--even though we have no need for it! And, it takes time to calibrate.

5. Too many labels on the map and lousy aesthetics with the lettering.


In the plus column, it shows the ISS against a map of the globe, lists current expedition members with photos of them, and includes a large gallery of Earth photos taken by the astronauts (they're beautiful, and each has a brief caption once you tap on it and open it up).

For now, the app has been moved to the back launch pad. :-). Hope these things get fixed soon.

Passes function needs redesign

Need to have the option to turn off the compass calibration and just have north always point up on the screen, then plot out the path against that fixed north. I should not be forced to calibrate the compass each time I want to view a pass. This isn't at all convenient when I am laying down, looking over all the upcoming passes. Currently there is a mismatch between the direction details and the plotted path. And not only does north continue to swing around, but the path is plotted incorrectly - often 180 degrees off! It seems like these bugs may all be related to the original calibration so it would be really nice if you would just allow me figure out where north is on my own.

Fantastic execution

This is the way you build data-driven apps. It's amazing how many people are unaware that the ISS passes over their heads almost daily. This app presents the information beautifully and I use it daily. It's also the ultimate party trick if you're with a group at the time of a pass ("Hey guys check this out!"). Well done.
