Hygrometer - Relative Humidity is a specialized application designed for measuring atmospheric relative humidity. This free utility caters to users with compatible devices featuring humidity sensors, offering direct readings in percentage format. Additionally, it provides a digital display that calculates the condensation dew point temperature based on current weather conditions at the user's location. For devices lacking a humidity sensor, the app retrieves data from local meteorological stations to present the measured humidity and a 48-hour trend forecast.

The app utilizes the Meteorologisk institutt of Norway's NRK weather web service for outdoor humidity information, ensuring accurate and reliable data. Users can enhance their experience by enabling optional altitude information through the Open-Elevation web service. Hygrometer - Relative Humidity serves as a valuable tool for anyone needing precise humidity measurements, making it an essential addition to the utilities and tools category on Android.
