Almost there, but needs more sources

Dark Sky just isn’t accurate for everyone. Great design, though.

Looks nice, but a little buggy

Found on /r/Apple. Radar map timeline doesn’t seem to work. It also doesn’t show precipitation on the radar. When I hit the current location button in radar, it puts my location in the bottom right side of the radar map. On the home screen of the app, the hourly forecast doesn’t scroll like I think it was intended to. You have to hit the dots to go to the next hours in the list.

It looks good, but currently doesn’t beat accuweather for me.

Great start, some improvements needed

First off, great app! Clearly a lot of time and labor went into this.

There need to be some refinements to make this a 5-star app. For example, when I open the map, it always centers on a neighboring state (Indiana) and then I have to manually locate myself (Kentucky). Not a huge problem, just more of an inconvenience. Also, when I try to enable notifications in the preferences tab, I can’t. I’d like to enable notifications, but can’t seem to get it to work.

Overall, good app, just some slight refinements needed.
