Psychrometer °F

I have been using this app for about two month. The only fault I could find is the ads. Personally, I would like an option to pay for an ad-free version. But the developer had done a good job of minimizing the impact of the ad. I have checked the results against a thermodynamic program that I use for process simulation. The programs match up. I have found this app to be easy to use and intuitive. If one is an HVAC professional, this app and a good hygrometer are just what one needs to “get it right.” Way cool. UPDATE: I discovered that the developer has a different version called CalcComfort that includes a pro version that deletes ads and includes additional features like Frost point for temps below freezing. Excellent.

Excellent. Especially for free and the ad doesn’t dominate the app like most free apps. It also is t from and center in fact it sits lightly at the top and sort of blends in unnoticeably.

Used the app to calibrate humidity readings of a home weather station.
