Thank you for understanding a point of ineligible way promo.

Hello, Red icon Windy app developers!
As far as I know there is no any official or unofficial "Windy" app. There are two "Windy" application with similar but different functionality. In our kite circles we call your app as "Red Windy" and the second one as "Blue Windy". No one court has decided it's an exclusive name.

But I agree with topic starter that this way to differ the applications is too aggressive and look like Russian phobia.
