This app uses the barometric pressure sensor found in the iPhone 6, 6s, 7, 8, X (including Plus models) and iPad Air 2, Mini 4 as well as iPad Pro (all sizes) and the newest iPad.
You need one of these devices in order to use this app!
It is not compatible with iPhone SE and older iPhone and iPad devices without this sensor!

This App features a Barometer for weather, an Altimeter for outdoor activities, a barometric Trend and a Notification Center Widget.

Even without the optional In-App-Purchase this is a fully functional Barometer with absolutely no draw-backs and all important features accessible. Always without ads! (See "Pro Features" at the end)

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. The new iPhones have a barometric pressure sensor built in so this app works completely without internet. The handy marker helps you keep track of changes in the barometric pressure and let's you predict weather changes! Please realize, that a single barometric pressure reading is not enough to tell the current weather situation but the barometric pressure and its change over time is a very good indicator for weather
