Altimeter vs Pro Altimeter for Watch

While traveling with a vehicle (car, bicycle, etc.), while hiking or climbing, you can instantly discover your location and altitude, direction, geographic coordinate, address and atmospheric pressure on the map. While following your direction on a detailed compass screen, you can also monitor the change in altitude. You can share the photos you take with your loved ones, including your altitude, geographic coordinates and address information. Depending on the shooting angle, the compass direction is also included in the photos. DISCOVER YOUR HEIGHT FROM SEA ON THE MAP (Normal Mode) You can instantly discover the information of your location on the map - Altitude (elevation) above sea level - Open air (atmosphere) pressure - Latitude and longitude coordinates and address - Speed in motion - Direction with a detailed compass FOLLOW YOUR HEIGHT FROM SEA ON THE MAP ON THE MOVE (Track Mode on the Map) On the map when traveling in a vehicle (car, bike, etc.), hiking or climbing, you can instantly track your location and the change in information - Altitude (elevation) above sea level - Open air (atmosphere) pressure - Latitude and longitude coordinates and address - Speed in motion - Direction with a detailed compass FOLLOW YOUR HEIGHT FROM SEA ON THE COMPASS (Compass Mode) While traveling with a vehicle (car, bicycle, etc.), while taking a walk or climbing, you can instantly track your direction and the altitude of your current location SHARE YOUR PHOTO WITH YOUR LOVED ONES WITH HEIGHT AND DIRECTION INFORMATION (Sharing Mode) While traveling with a vehicle (car, bike, etc.), hiking or climbing, you can share the photos you have taken with this information - Height, pressure, coordinate and address information will be on the photo - Depending on the shooting angle, the compass direction will be added to the photo YOU CAN ACCESS ALTITUDE AND LOCATION INFORMATION FROM APPLE WATCH IMPORTANT REMINDER ABOUT CALCULATION METHOD AND ACCURACY - The coordinates of the altitude and location are calculated using the GPS signals of the device used - There may be differences in the measurement values ​​depending on the GPS signal quality of the device's location - Just below the height value, the accuracy value of the measurement is given instantly in meters - Compass accuracy may be affected by magnetic or environmental interference UNLOCK ALTIMETER PRO - Use Altimeter without ads - Unlock point elevation - Unlock weather information - Access all current and future Pro features SUBSCRIPTION OPTIONS - Monthly: Renews every month.

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.
