pretty—but useless for photography

This app makes a great first impression with its amazing graphics. Its lunar calendar and control over the date make it seem like it's got everything you'd ever want in a moon phases app + more. However, once you look past the bling, the app has very little to offer a photographer. As has been pointed out in other reviews, the app doesn't provide moon rise and set times. You need to find another app to get this basic information. Maybe that's a good thing because, despite having permission to use my location, the sunrise/sunset times are off by 3:06 (sunrise) and 3:12 (sunset). Obviously not a DST issue. You cannot set a location manually. Then there's that cool constellation chart. It is this feature that makes me think I'm missing the whole point of this app. If I'm reading it correctly (and I don't know if I am), it shows the constellations visible at a particular time of day and year, as well as the planets and their height in the sky (?) but, again, from what location?

Great app for seeing Lunar phases

This app gives tons of info on the moon and other planets. The one thing I would like to see though is the time of the moon rise where Im at. I can't believe that's not in the info that's included. Otherwise, this is an awesome app!

Good but not fully accurate

This app has really nice graphics and stats, but there are a few minor inaccuracies. The star chart for example is missing the constellation Ophiuchus, which officially crosses the ecliptic along with the other 12 constellations. I believe this was made official by the IAU (International Astronomical Union). Secondly, Capricorn should be spelled Capricornus. Other than that, great app!

Beautiful graphics

Excellent graphics and lots of info. I would like to see moon rise and moon set times. Also a graphic showing moons actual orbit around the earth (I think it is oblong) Also a graphic showing how the lunar year relates to the solar year since the lunar year is 6 hours shorter. I would be happy to pay for an educational moon app.

Impressive extras, but basic setup needs work

I was impressed by the quality of artwork and extra information presented in this app. At first glance, it would seem to be overkill, unless you are an avid astronomy buff. But the basic setup information keeps this app from rating 5 stars. It does not accurately handle time zones. Entering a minus sign (US is GMT-x) results in sunrises in the evening, and sunsets in the morning, and entering custom latitude and longitude isn't straightforward. And it doesn't handle DST adjustments.

It doesn't update my location even though I have location services turned on for the app on Windows 10.

Beautiful--and I mean truly gorgeous--but Stupid

The graphics on this app are perfection. It's a shame the astronomical information they convey is rubbish. This ought to rate 5 stars and almost does.

The best app on windows 8

This is the best app I've used on windows 8 so far.. Nuff said.
