Ratings and reviews

The classic iWindsurf layout on the website is much better. For example, there is an alphabetical list of all my favorite sites on the left side of My iW page. Also the list of windy sites on that page is more compact with a horizontal bar to represent the wind speed. On the page for each site I can click a link to see the map of the surrounding area and I can jump to a nearby site from the drop down list. etc.

👎👎👎 Not OK, app used to be better before the update/upgrade. Can't access many stations I used to without paid subscription anymore. Been using the app for over 6 years, stations that used to free are no longer. But based on your response, you're calling me a liar! DEFINITELY NOT OK! Taking my review down to 1 star. Will be looking for a new wind app now, thats for sure!!!! I won't be paying for your app, ever. P.S. in the future, dont LOSE business and CUSTOMERS by insulting them!

great information though app navigation is a bit clunky
