Way off!

I’ve used this app for a few years and always loved it. This winter in Montana it is so far off it’s a joke. Right now it’s snowing and has been since the middle of the night. The app says it’s clear. It’s says we’re 47°F. I don’t think we’d be buried in snow at that temperature. One day I checked and my watch and the news said it was 12°F , the app said -21° F. I made sure it wasn’t on Celcius or anything else that could be causing this. It’s just so far off these days it’s a joke. Please fix it. This use to be a app that I loved and used, which is why I give it 3 starts instead of 1.

Server unavailable

Update to previous reviews:

The comment immediately below still applies. In addition, and as noted by other users, I frequently get a server unavailbale message, so it cannot update the weather. Also, there have been some weird display issues - in particular, sometimes the 3 hourly forecast shows under daily forecast - and vice versa. I note that the app has not been updated in 2 years, and the Vimov twitter feed has not had any posts for almost 4 years. It looks like the developer has just given up. Maybe time to look for a new weather app - a shame.


Addition to my original review:

Periodically the drop down menu stops working and I have to restart the computer to get it working again. This seems to happen in particular when I make a change in the main app, such as adding a city.


I have weather for both the US and UK set up. A UK town is set as default. Imagine my surprise when the temperature icon was lit up in red indicating a severe alert even though it was sunny outside. I went to the app and saw that the sever alert was for a town in the US, but the actual text said that there was a severe thunderstorm over Scotland OR over a town maybe 100 miles away from the town in the US. The app obviously gets confused. Sort of wish I hadn’t bought it on sale over the weekend.

Also, the main app needs a complete overhaul. It is rather ugly, and the animations add nothing, but instead get in the way.

After “Temps” turned off their service...

… I was forced to go looking for yet another weather app (I used Degrees Pro before that and it quit working as wll). Clear Day is very nicely done. I like the layout and dropdown that is displayed when you hover over the status bar icon. It displays all the information I’m interested in in the full screen mode but it would be nice if one had the option to display a second parameter in the status bar along with temperature—for instance, humidity or wind speed (for pilots). But this is simply a request—the app itself seems to do everything it listed in its description. Very nicely done!
