Please Note that on older devices such as the 4S, 5, 5S and 5C as well as on any iPod Touch and iPad Models older than iPad Air 2 or iPad Mini 4 as well as the Apple Watch 1 and 2, this app will not be able to read barometric pressure values and not display any useful information.
This app uses the barometric pressure sensor built into all the newer iPhone, iPad and Apple Watch Models sold after 2016 with few exceptions.
This App features a Barometer for weather, an Altimeter for outdoor activities, a barometric Trend and a Notification Center Widget.
Keep an eye on the barometric pressure and be your own weather forecast! This little app uses only GPS (optional) and the new barometric pressure sensor to calculate the barometric pressure used in weather forecasts.
Just set your reference pressure and altitude in order to use the Altimeter for checking how high up the mountain you have climbed (works for other activities too).
