I've tried to like this app, but the developer keeps failing to fix its shortcomings.
I got it because the dev's site says "Helpful widget for your Notification Center in OS X Yosemite: see the weather forecast at a glance!"
Well, sort of.
In order for the widget to stay updated, the app itself must be opened. It's supposed to display weather symbols for four days. If you don't open it for two days, then only the most recent 2 days are shown, the others are blank. If you don't open the app for four days, the widget is all blank.
As I've told the dev., I don't WANT to open the app every day and then close it just to keep the widget updated. Widgets are supposed to function independently, otherwise what's the point? Just open the app.
Yes, the GUI is nice, but that's not the point. The widget, when it's been updated, usually shows me all I need. If for some reason I want to know what time the sun sets, THEN I'll open the app.
