Barometer and Compass is a free Android application developed by Dmitriy Lapayev in the Utilities & Tools category. As the name suggests, this app is designed to test the sensors of your device, specifically the atmospheric pressure sensor for the barometer and the magnetometer and accelerometer for the compass.

The main feature of Barometer and Compass is the "Sensors" page, where you can view a list and data received from the sensors. By selecting a sensor, you can access detailed information about it.

In addition to the sensor testing, the app also includes a widget (2x1) for the barometer, allowing you to easily view and save data at specified time intervals. The stored and current data of atmospheric pressure are displayed in a graph, providing a visual representation of the changes over time.

Another useful feature of Barometer and Compass is the ability to display a compass on a map, showing your current location and the magnetic declination for the selected coordinates. This can be particularly handy for outdoor activities or navigation purposes.

Overall, Barometer and Compass is a handy tool for testing the sensors of your Android device, providing valuable information about atmospheric pressure and magnetic orientation.
