Windy

First, 'Forecast' seems to think I'm 25 miles from lat/log I enter/set. Seems to use cable IP address... some sites think I'm 25 miles away, other sites get it right. Close but no cigar.
Second, has a mix of US and meter 'default' settings and the only way to 'save' settings is to create login and give them your personal information. Wish companies would realize the best way to protect customer information isn't a "Privacy Policy" but just don't collect the information!
Third, use mainly for radar... won't keep the 'pressure' overlay set in saved link and have to re-enable. And doesn't show the pressure altitude - sometimes the 'rain' seems to move counter (clockwise rather than counter-clockwise) to the low pressure area.
Mouse wheel doesn't 'zoom', have to use to + / - buttons to zoom.

Windy is a great app and has extreme attention to detail. It is user-friendly and easy to navigate. There are personalized settings to curate the app to your needs/preferences. Not only can you view the wind patterns, but you can check on weather news and track hurricanes. There are many more elements to Windy and you can make a personalized page for all of your favorites on the website. One way to make it more useful would be to make it clear that it is easier to navigate by dragging the map around rather than using your track pad in your are on a lap top.

Excellent software. Very reliable weather forecasting up to about 3 days ahead. During the day it seems reliable for weather forecasting almost to the hour.
