Note: This app uses the barometer sensor on the iPhone 6, iPhone 6 Plus or the iPad Air 2 and will only work on those devices.

Pressur is an elegant and useful tool to track barometric pressure measurements using the built in sensor on your iPhone 6, iPhone 6 Plus or iPad Air 2. Unlike other simple barometer apps, Pressur records atmospheric pressure not only when you are using the app but also occasionally updates in the background and saves these readings so you can observe pressure trends over time to anticipate weather condition changes. Best of all Pressur does not require a network or GPS so it's battery impact is minimal and can even be used offline. We think you will find that "Pressur" actually makes "pressure" fun to observe.

Here are some features of Pressur:

- Switch between the following units of measurement: kPa, mmHg, inHg, mBar
- Digital and simulated analog gauge graphic readouts
- Pressure rising / falling indicator
- Measurement log with pressure measurement and date/time stamp
- Animated, interactive graph to view readings based over time
- Trend report for maximum, minimum and average pressure measurements
- Today Widget

There is also an in-app purchase option available to unlock even more features including:

- Extended trend/graph timeline options
- Ability to view graph full screen in landscape mode
- Ability to add a beautifuly animated trend graph to the Today Widget
- Optional pressure background change notifications
- Custom pressure change alert which notifies you if the pressure has risen above or fallen below a pressure of your choosing. (a great option for people who suffer from migraines caused by pressure changes)
- Advertising banners removed

** For best results remember to keep "background fetch" enabled in your settings and allow the app to run in the background.
