I just paid for the auto renew premium edition of Windy and now that I have been learning how to use it properly I've discovered that you do not have Humidex or Wind Chill charts available, and apparently you have no plans to include them.
I use the Humidex (summer) and Wind Chill (winter) every day to determine if it is safe to walk and how to dress. It is sad that although I just purchased the auto renew windy app that I still have to keep the weather network app around as it provides these items for me.
I guess that now I will need to evaluate whether I cancel my subscription since I don't want/need to have two apps.
