Calculate heat loss and humidity issues in building structures. Input air temperature, humidity, and material layers to visualize temperature and dew point changes. Supports both Celsius/Fahrenheit and cm/inches.



This application allows you to quickly calculate the dew point or relative humidity of the air. Input any two known values (dry bulb temperature, relative humidity, or dew point) to determine the third. It's a useful tool for weather enthusiasts and those with home weather stations.






This utility app functions as a thermal camera, offering a wide temperature measurement range. It allows users to capture images and videos, track high and low temperatures, and set custom alarms for temperature thresholds. The app also supports various regional temperature measurement modes.
