App not well maintained
I use this app heavily on iOS devices, and it works great. The OS X version has problems though, and the devleopers are not maintaining it well for recent OS X versions (e.g. El Capitan). It used to work better for Yosemit. For example, scrolling does not work well in the windows, you are unable to click on a day and get the hourly forecasts like on the iOS version, and there are long delays (not network related) when toggling between different cities. Users also have limited options for how they can resize the window.I would not recommend buying this app. Find something different, or stick to the iOS version.
