Barometer & Altimeter Pro 4.1.1 ios官方版

This app uses the barometric pressure sensor built into all the newer iPhone, iPad and Apple Watch Models sold after 2016 with few exceptions. You need one of these newer devices to use this App. See below which older iPhone, iPad and Apple Watch without this sensor are not supported!

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). No internet connection required, no data transmitted - runs on your device only!

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 changes!

Now you can also see the trend in barometric pressure with graph charts displaying the measurements taken during the last 30 days! (6h, 12h, 24h, 3d, 7d, 14d, 30d)

The Altimeter helps you track your altitude changes based on the change of pressure. 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). The App does not use GPS for the Altimeter.

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. The first generation 4-inch iPhone SE is not supported - the new SE (2020) is!

All basic features, the Barometer, the Altimeter, the Trend and the Widget are completely free to use for everyone and are fully functional at maximum accuracy available. No ads!
The only features with restricted access via In-App-Purchase are listed at the end under "Pro Features". Those are nice to have features for power users or those that want to show their support for the App!
