Been using this app for 10 years App always had an upgrade feature, but the app has ads so most weather stations were free to use for current condition and forecast. Now the greedy developers made the any feature an upgrade. All stations say experimental and can't see anything. Just used this app like a month ago.. used to have 4 stars now it's 1.

Randy, W H A T? We have not changed anything. Most of the stations are Free to use; you must have hit some option that changed what you were looking at. It's unclear. Anyhow- our Customer Support team can help you with whatever issue you are having! Give us a jingle at: App Main Menu > Settings & Help > Contact Us.

There is so much more, beyond the first screen, AND the first screen data may be outdated. Select the station for more details, beyond just the wind!

Great app for wind direction and velocity. I really like the ability to select multiple forecast models at the same time.
