Barometer and Altimeter is a mobile application that allows users to measure atmospheric pressure and altitude. The app uses the built-in GPS and pressure sensor/barometer to provide accurate height measurement above sea level and barometric pressure readings. If the device does not have a barometric sensor, the application retrieves atmospheric pressure data via the Internet from the nearest meteorological station. The app also features an automatic altitude and atmospheric pressure calibration algorithm based on data from local meteorological stations.<br/><br/>In addition to measuring atmospheric pressure and altitude, the Barometer and Altimeter app provides users with GPS coordinates, the name of the location, and country. It also provides information and current weather data from the local weather station, including outside temperature, wind speed, visibility, humidity, and hygrometer (if the device is equipped with appropriate sensors). The app is useful for a variety of activities, including health and medical monitoring, fishing and sailing, sports and tourism, weather prediction, location checking, and aviation.<br/><br/>The Barometer and Altimeter app is free, easy to use, simple, and handy. However, some portable devices such as tablets, phones, and smartphones may not have a built-in pressure sensor. In such cases, the measurements may be less accurate as they will be based on data from the local meteorological stations. The app is constantly being developed, and users are encouraged to provide feedback and suggestions for improvement.<br/><br/>Overall, the Barometer and Altimeter app is a useful tool for anyone who needs to measure atmospheric pressure and altitude. It is easy to use, provides accurate readings, and is available for free. Whether you are a fisherman, sportsman, tourist, or pilot, this app can help you monitor the weather and make informed decisions.
