This app is an app that calculates comfort. It calculates heat, cold, dryness and moisture and tells you the comfortable range.You can easily change the value with the dial, and the temperature is displayed in color in an easy-to-understand manner.
By inputting either temperature and humidity, dew point temperature or wet-bulb temperature, the following air conditions can be calculated accurately.
DrybulbTemperature (°F)
WetbulbTemperature (°F)
DewPointTemperature(FrostPoint) (°F)
RelativeHumidity (%rh)
MixingRatio (Humidity ratio) (gr/lb)
AbsoluteHumidity (gr/ft3)
Enthalpy (btu/lb)
SpecificVolume (ft3/lb)
AtmosphericPressure (InHg)
VaporPressure (InHg)
SaturatedVaporPressure (InHg)
Temperature–humidity index(Discomfort index)
(Good indication in the temperature range of 68 to 82°F and humidity of 30 to 60%)
Easy to input by dialing.
You can automatically enter outside temperature and humidity from the weather information.
(Please allow use of location information.)
If you use a psychrometer, please choose from 3 types.
(When not using, please use it as it is as a Assmann.)
Asssmann ... Aspirator psychrometer. It is a forced ventilation type.
Natulral ... August psychrometer.Simple type without forced ventilation.Wall-mounted.
Sling ... Sling Psychrometer.Type that swings around by hand.
(If you press the reset button or the outside air button, it will return to the ventilation type. With the exception of the ventilation type, only wet bulb input is possible.)
The following calculations can be easily performed without a psychrometric chart.
By setting (fixing) the input mode to the dew point input ℃ DP and increasing/decreasing the upper dial, the heating/cooling change can be read.
By setting (fixing) the input mode to wet bulb input °C WB and increasing/decreasing the upper dial, changes in humidification/dehumidification can be read.
For steam humidification, set (fix) the input mode to humidity input% and increase/decrease the lower dial to read.
The formula of SONNTAG is used for the calculation of saturated water vapor pressure, and SPRUNG and FERREL are specified for the calculation formula of each water vapor pressure. Relative humidity is calculated according to WMO.
This app does not measure the value of your current location. Get weather information.
The range of values that can be entered is wide in consideration of usability, but if you enter an extreme value, the error will increase and an error will occur.
Also, please note that the minimum digit will be different due to rounding and other calculations. Therefore, the numbers may be blurred when switching between modes.
We have made every effort to ensure the accuracy of the calculation results, but we do not guarantee their accuracy. Please note that we are not responsible for any damages, losses, disadvantages, etc. that occur during use.

Just what I wanted
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.
Terrible
Confirmed the values by plotting on a psychrometric chart and it wasn’t even close!
Review
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.
Very Useful for Home Weather Station
Used the app to calibrate humidity readings of a home weather station.
