@whitmart14 I would argue that Windy is not like all the other apps you reference that provide free 10 day forecasts. If this was true why not just jump ship to one of those apps and get the data you want for free? Personally I am a Windy subscriber because the data they provide, and the services they offer is much better than other weather apps. This is why I became a Premium subscriber. After using many weather apps for years, most of them free, I saw the value that Windy provides. They provide what others don't which is worth my money, and the fact they provide a bunch of this for free is a bonus.
I understand how paying for something that used to be free is frustrating but I think its great that there was a period of time where we got this amazing service for free.
