Barometric Pressure Altimeter
Pro Altimeter for Watch is the newest Watch app from Hunter Research, developer of the popular outdoors app TheodolitePro Altimeter uses the high-fidelity barometric pressure sensor in the Apple Watch to measure and compute altitudeAlthough this is a Watch app, it has the same features, capabilities, and accuracy as the Pro Altimeter app for iPhone and iPad, just in a smaller form factor on your wrist! Pro Altimeter has a dead simple interfaceBarometric altitude and GPS altitude are displayed in large easy to read numbers, with available units of feet or meters, and realtime accuracy estimates from the hardwareAt bottom are calibration and settings buttons. The display offers highly-readable color schemes of luminescent green on black, white on black, and midnight red on black. Proper calibration is necessary to measure altitude from barometric pressure (this is why a pilot "dials in" the cockpit altimeter before taking off). Pro Altimeter offers numerous methods for calibrationchoose the easiest and most convenient: 1. Use GPS altitudeThis method correlates the measured local barometric pressure with the altitude measured by GPS. This method can be..
