Klimatherm RaumKlimaRechner is an all-in-one app for capturing and computing all relevant data about room climate. The app enables users to calculate various aspects of room climate, including Taupunkt (with T@80%, T@70%, T@60%), U-value, humidity, enthalpy, temperature unit converter, and fRSi value. The fRSi value helps to identify potential mold growth spots and heat bridges by keeping the outdoor and indoor temperatures constant and varying the surface temperature. The app also features an automatic logging function that saves all calculations performed in a text file on the device. The log file is editable and can be copied to other devices.

In addition, the app offers online supplementary material about air quality under the "Online Info" section in the settings menu. With its easy-to-use interface and quick results, Klimatherm RaumKlimaRechner is an ideal tool for managing room climate.
