Does not update
This app has the potential to be good, but for now it is a total waste of time. It doesn’t update. So, if you open it on Friday, and the temperature is 65 degrees, then if you look it again a week later (without having rebooted your Mac), the temperature will still be 65 — even though the actual temperature may have changed by 20 degrees. Whatever the weather is when you open it, that’s how the weather stays — at least on your desktop. An app that doesn’t update is pretty much useless to me.
