Humidity Window - Stoßlüften

I have been doing manual checks/calculations for years to try to figure out the best time to do an outdoor fresh air exchange without bringing the stifling humidity of NC inside. This simple app makes that super easy and I only wish I knew about it sooner. I discovered this app accidentally when looking for a Home Screen widget that would display the outdoor humidity, which it does! This is officially one of my favorite apps of all time and I will be recommending it to friends/family/anyone who cares about indoor air quality. Thank you to the developer for creating this app!!!

My only nitpick is that the optimal ventilation window section at the top uses the lowest daily outdoor relative humidity rather than lowest daily outdoor absolute humidity to tell you when to open your window. This usually results in it telling me to open my window during the hottest hours of the day when the RH is lowest, but the AH may still be higher than other times. The humidity calculator section at the bottom works exactly how I’d want: comparing the outdoor AH to the indoor AH to determine whether you can open the window. I think the humidity window section should highlight the hours in the day with the lowest AH as the most likely opportunities to open the windows.

Must have for humid Florida.
