Barometer and Altimeter is a free weather application developed by Pegasus Software for Android devices. It uses the built-in sensors of your device to provide you with accurate barometric and altimetric readings. With its customizable features, the app is suitable for both casual and professional use.

One of the main features of this app is its ability to track altitude. It also provides charts with various pressure types such as hectopascal, milibars, millimeter of mercury, inches of mercury, and atmospheres. You can view altitude in meters or feet, and there is a homescreen widget that shows the trend. The app also records the minimum and maximum pressure readings.

The app is customizable and can normalize pressure by adding two or more locations and displaying a chart with values compared to the home location. However, this functionality requires location services or an active WIFI connection. The app also requires an internet connection to calculate altitude from pressure, which can be disabled by the user to avoid data costs. The app comes with integrated help and debugging features, without any ads.

Overall, Barometer and Altimeter is a reliable and accurate weather app that can be customized to meet your specific needs. It is suitable for outdoor enthusiasts, pilots, and anyone who needs to monitor barometric and altimetric readings regularly.
