Ratings and reviews

This looks like a decent application, but it's wrong. It always seems to want to use a time zone at least an hour to the east, with the sun at noon in the southeast instead of due south (??). So it's certainly inaccurate. Fix these errors, or at least give the option to use the time from the phone in calculations instead of what appears to be some arbitrary time, and it might actually be good.

Absolutely Fantastic App. Use it all the time, constantly updated and all the features work more or less as exactly advertised. My only problem is that I can't adjust the size of some of the larger widgets. The larger Samsung Galaxy series phones have a 5 wide app screen and some of the widgets are limited to a 4x2 size, just kind of nicks at my OCD but it's nothing that ruins the app.

Moved from New Mexico, around 34° N, to Fairbanks, Alaska, 64+° N three years ago. We can gain/lose over 40 minutes of daylight per week at certain times of the year, and the sunrise/set are 65 degrees off of due east and west at the solstices. Downloading this app almost immediately after my arrival kept me from losing my mind trying to keep up with what the sun is up to. It is also absolutely beautiful from a data presentation and accessibility standpoint. Well worth paying to lose the ads.
