Elevation vs Pro Altimeter for Watch

Find your current elevation, altitude, and height above sea level easily with this altimeter/barometer app. ## Elevation Finder ## This app helps you observe the elevations of all locations on the surface of the earth by simply touch and move the map around, or input the address/location name. You can also find the elevation of your current location by using online database, built-in GPS, or barometer on your device. Elevation data benefits flood prevention, prediction of water levels in rivers, lakes, and seas, etc. Thus, knowing the elevation of places is very crucial if you are looking for a flood-free house, or planning for a hiking trip, and more. ## Cloud-based Altitude Data ## The easiest way to find altitude of any location on earth. By simply point on the screen, you can get the elevation data from a coordinate location point. “Range Mode” is available for altitude comparison (by graph and line) of each point between two selected locations. ## GPS Altitude Data ## Use built-in GPS on your device to determine the altitude of your current location. The altitude data of the area you walked-through will be recorded and displayed as a multicolored line on the map. The colors presented on the line indicate different heights. Precision indicators (horizontal resolution and vertical resolution) are displayed on the screen. ## Barometric Altitude Data ## Use built-in barometer on your device to determine the elevation of your current location. You can either measure the elevation from raw barometric data, or relative pressure from sea-level. Like GPS data, the result is displayed as a multicolored line. To get the most accurate data, it is recommended to adjust the sea level pressure and temperature prior to the measurement, and set the offset or calibration value if necessary. ## Standalone Barometer ## You can use this app as a standalone barometer. ## Air Pressure / Altitude Calculator ## Atmospheric pressure and/or altitude at your current location are calculated from known altitude, pressure of the location, temperature and/or sea level pressure. ## Support of Coordinate Formats ## This app not only displays regular latitude and longitude data, but also supports many coordinate systems such as, Universal Transverse Mercator (UTM) coordinate system and Military Grid Reference System (MGRS) and more. ## Export of Data ## From this app, you can export many useful information including timestamp, altitude, pressure, and coordinates.

Pro Altimeter for Watch is the newest Watch app from Hunter Research, developer of the popular outdoors app Theodolite. Pro Altimeter uses the high-fidelity barometric pressure sensor in the Apple Watch to measure and compute altitude. Although 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 interface. Barometric 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 hardware. At 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 calibration -- choose the easiest and most convenient: 1. Use GPS altitude. This method correlates the measured local barometric pressure with the altitude measured by GPS. This method can be used when your device has a clear line of sight to the sky and a reliable GPS fix with good accuracy that you trust. 2. Manually enter altitude in feet or meters. This method correlates the measured local barometric pressure with known altitude from landmarks, elevation benchmarks, trail markers, topo maps, land surveys, etc. 3. Manually enter pressure. If you have a weather station, weather report, or METAR report with equivalent sea level pressure for a nearby location, this can be used to correlate local barometric pressure to altitude. Pressure can be entered with units of inches Hg, kPa, or mb. 4. Check local airports. With the tap of a button, Pro Altimeter will locate the five closest airports within 100 miles (160km) of your present location anywhere in the world, and pull in METAR data. From that list of five, pick the airport of your choice and Pro Altimeter will import pressure data for calibration. Once calibrated, Pro Altimeter keeps track of the time since its last calibration. Because weather and local barometric pressure change over time, the app will warn you when 6 hours have elapsed since the last calibration by flashing the "CAL" button. You should calibrate as frequently as practical -- for example, on a hike, calibrate whenever you pass a trail marker or elevation benchmark, or hourly. But at a minimum, calibrate at least every 6 hours or whenever weather changes in your area. Pro Altimeter runs on all Apple Watch models running watchOS 9.6 or later. NOTE: The app requires user permission to access Location Services and Motion & Fitness in order to operate properly.
