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).
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.
Using changes in pressure, the app displays an approximate elevation change from a reset point that you control.
View raw or adjusted pressure quickly using a Today Widget in Notification Center! This functionality requires an in-app purchase.
This app displays the current pressure as detected by the barometer sensor inside iPhone.
Measure altitude change in meters or feet.
If no network connection is available, the altitude is obtained directly from your GPS.
This means no network connection is required.
