Barometer Plus vs My Altitude and Elevation

Barometer Plus app measures air pressure and altitude using your device's built-in barometric pressure sensor. Because air pressure changes usually indicate a weather change, you can use this app to monitor and predict short-term weather variations. People suffering from migraine, headaches, or joint pain can monitor how barometric pressure impacts their mood. Fishermen can monitor the atmospheric pressure for right-time fishing. FEATURES: • The app contains a barometer and altimeter with a personalization graphic in classic analog style. It also displays the current temperature and humidity. • Display barometric pressure (sensor value) or mean sea level pressure (MSLP - value used in weather forecast services or stations). • Units support for pressure: mb, inHg, kPa, atm, Torr, psi, hPa, mmHg. Units for altitude: meter, feet. • Calibrate the barometer using altitude/location from the GPS. Calibrate the altimeter using the nearest airport information/METAR, or manually enter the QNH of the nearest airport. Offset sensor output value. • Measure the height (building/mountain/hiked/climbed) using the "Relative Altitude" feature (can be enabled in the app's Settings). • Notification about pressure change. "Notification custom rule" for you to define how and when the app sends notifications. Notify when air pressure changes indicate that extreme or worse weather may occur. • "Pressure Tracking" and "History Graph" require "Background App Refresh" or "Always Location Service" with "Exact update interval" (paid feature) enabled. • "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data. • Export history to CSV format and Today widget (paid features). • This app is the digital version compared with an aneroid or mercury barometer and can be adjusted to MSLP with additional features. CUSTOMIZABLE: You can change your barometer/altimeter appearance with: • Seven different housing colors. • Black, white or blue disk background. • Four different app backgrounds. • Three different types of needles. • Marker needle for easily monitor. • Dark or light Today widget theme. NOTES: • App only works on devices with a barometer sensor, such as iPhone 6/6s/7/8/X/11/12/13 (including Plus models), iPad Mini 4/Air 2/Pro, or later. • Weather icons on the dial: This only shows the air pressure trend like in an analog barometer. • Each time your device reboots, open the app for tracking with the "Exact update interval" feature work. • You may take the phone/tablet far away from computers, cables, and other magnetic sources to get accurate results.

My Altitude and Elevation uses web services to get your precise surface elevation based on your current location. This is far more accurate than the elevation data provided by your device. But there's so much more you can do with My Altitude and Elevation. Try it and see! You can select from the best sources of elevation data, including: 1. Location based altitude from NASA's Shuttle Radar Topography Mission. 2. Satellite based altitude (GPS altitude) corrected to height above mean sea level (AMSL). 3. Get actual land survey altitude values for your location from the United States Geologic Survey - available for customers in the contiguous United States, southern Canada and Mexico. 4. Devices equipped with a barometer sensor can also obtain pressure altitude which is converted to elevation above sea level. For the most precise readings, calibrate the pressure altitude. Barometer and Altimeter features: - accurate height measurement above sea level (from GPS and other sensors), - accurate measurement of barometric pressure (if the device is equipped in pressure sensor and check data available online) - GPS coordinates, name of location, country - information and current weather data from your local weather station (if available). - outside temperature, - wind speed, - visibility, - humidity, hygrometer (if device is equipped with appropriate sensors). App Features: - Elevation from see level in meter (metric) or feet (imperial) - Change between metric and imperial systems by tapping on reported elevation - Current location coordinates including latitude and longitude - Barometric pressure in various units extracted from device sensor or calculated from altitude - Water boiling point at your current location - Current weather information including temperature, condition, humidity, wind speed and wind bearing - World Altitude, get approximate altitude (elevation from see level) of any location in the world - Save altitude data for reference - Take a picture and watermark it with elevation information and share
