You are talking about Pro version... Are you sure that you are on the right forum? Here you are on the community forum of windy.com and its mobile app. There is another app called Windy with a blue logo which sells a Pro version. But this app has nothing to do with this forum.

The main advantage of windy.com is that you get both ECMWF and GFS models free for you area.
Just download this app
on AppStore
on Google play.
