Thermometer - Hygrometer is a free Android app by HD-Team that provides users with accurate outdoor temperature readings in real-time. It also displays humidity, wind speed, and battery and CPU temperature. The app is a hygrometer, and the temperature displayed is that of the air and not the room.

The app is designed with a simple and delicate interface, making it easy to use. The temperature corresponds to the user's precise location anywhere in the world and is updated in real-time. The thermometer provides the most accurate temperature reading in Google Play and can be displayed in degrees Celsius or Fahrenheit. However, some devices may not have a built-in temperature sensor, and the app will use the device's electronic subassembly sensor, which may give a different temperature from the ambient air temperature. To obtain the most accurate temperature reading, it is recommended to leave the phone untouched for an hour.

The hygrometer displays wind speed and humidity, and fast location identification allows for outside temperature display. Internet connectivity is required to receive the temperature calculated on the app's meteorological servers. Overall, Thermometer - Hygrometer is a great tool for those looking for a simple and accurate way to check outdoor temperature and humidity.
