This app should be measuring dew point instead of humidity. Humidity at say, 90% would mean that its raining. It’s the water in the air. Raining doesnt have anything to do with mugginess, what people often mistake for feeling “humid”. Your hygrometer says “comfort” at the 50% mark. That would mean if it’s 50% raining outside, we are not comfortable? What is 50% rain? If it’s like today, 51degrees out (pretty chilly!), and it’s raining, it’s certainly not muggy. Yet your hygrometer says it’s “wet”. Waaay past comfortable. It makes no sense and it gives the impression that it is unbearably muggy, when in fact it’s only raining. If people want to know how muggy it is, they need to check the dew point, not the humidity. And this needs to be made known more and the meteorologists aren’t helping matters by constantly telling us about the “humidity”. “Estimating mugginess using relative humidity can be misleading since a high relative humidity doesn't necessarily mean high mugginess. For example, on a 40°F day if the dew point is 36°F the relative humidity would be 90%. This is a high RH (relative humidity) but it wouldn't feel muggy because the air temperature is cool.” Dew point (°F)Degree of Mugginess< 50Not muggy50-59Slightly muggy60-69Moderately muggy70-79Very muggy79+Unbearably muggy- National Weather Service
