WARNING: Only works on devices with a barometer (iPhone 6, iPhone 6 Plus, iPad Air 2, and newer)
ACCURATE BAROMETRIC SENSOR
This app displays the current pressure as detected by the barometer sensor inside iPhone. This means no network connection is required. You can get the current pressure anywhere your iPhone can go!
View raw or adjusted pressure quickly using a Today Widget in Notification Center! This functionality requires an in-app purchase.
A CORNUCOPIA OF UNITS
Measure air pressure in a number of different units: inches mercury (inHg), kilopascals (kPa), millimeters of mercury (mmHg), atmospheres, hectopascals (hPa), or pounds per square inch (PSI). Measure altitude change in meters or feet.
SEA-LEVEL AIR PRESSURE ADJUSTMENT
Use your GPS-determined altitude to estimate air pressure at sea level to compare with weather stations around the world! Uses super-accurate reference to find very accurate altitude based on GPS location. If no network connection is available, the altitude is obtained directly from your GPS.
APPROXIMATE ELEVATION CHANGE
Using changes in pressure, the app displays an approximate elevation change from a reset point that you control.
