Altimeter Barometer is a free and simple iPhone application that provides users with an altimeter and barometer function. With a large font display, it allows users to easily view their current altitude measured by GPS, as well as the sea level in meters (m). The app also includes a conversion calculator for users who prefer to view altitude in feet (ft).

One of the standout features of Altimeter Barometer is its barometric function, which utilizes the pressure sensor on iPhone 6 and later models. This feature comes in handy for users who want to track changes in atmospheric pressure and stay informed about potential weather changes.

It's important to note that due to the nature of GPS measurements, there may be some errors in the accuracy of the altitude readings. However, Altimeter Barometer provides a convenient way for users to get a general idea of their current altitude and track changes over time.

Overall, Altimeter Barometer is a useful tool for outdoor enthusiasts, hikers, and anyone interested in monitoring their altitude and atmospheric pressure on their iPhone.
