My Altitude

My Altitude uses GPS to determine your current location and displays latitude, longitude, altitude (above sea level), barometric pressure, and the local water boiling point. The app is free and offline-capable; an in-app purchase can remove ads and support ongoing development. You can also use NOAA data files for additional altitude reference on devices where sensors are less accurate, though sensor-based elevation is typically most accurate on newer devices.

Features include elevation in metric or imperial units, a tap to switch between systems, current coordinates, weather overview, and a world altitude lookup. Save altitude data for later reference, take snapshots, and watermark photos with elevation, coordinates, and timestamp before saving or sharing.
