Bar-o-Meter is a free lifestyle application available for iPhone. Developed by NETTuno s.r.l., this app provides users with various features related to altitude and weather.

One of the key features of Bar-o-Meter is its ability to calculate altitude based on the pressure measured from the device's barometer sensor. It also offers a weather forecast and displays pressure in different units of measurement. Even on devices without a barometric sensor, the app utilizes accurate internet services to provide pressure and altitude information.

The app includes a widget, allowing users to conveniently monitor pressure at all times. Additionally, Bar-o-Meter offers pressure and altitude charts, enabling users to visualize the variations over time. Another interesting feature is the Relative Altitude, which calculates how much elevation has been hiked based on the pressure measurement of the device.

With its multiple measure units and appealing animations in a Flat Design graphic, Bar-o-Meter provides an engaging user experience. The app is constantly being updated with new features, and the latest version includes improvements such as the option to remove ads through in-app purchase, a new Wiki button, and the ability to take a picture with barometric data in overlay.
