Apple may find a way to include another sensor in the upcoming “iPhone 6.” According to 9to5Mac, references in iOS 8 and XCode 6 point to hardware with an integrated barometer.

The CoreMotion APIs in the beta software offer a glimpse into a new framework that needs next-generation devices.

A built-in barometer could open up a number of possibilities. Probably the two biggest include altitude tracking and weather forecasting.

With a barometer, apps could help users determine their current altitude or change in altitude, like when on a run. A barometer is also used to help forecast upcoming weather changes because of changes in air pressure.

Along with the “iPhone 6,” Apple could also include a barometer in the next generation of iPads and the long-rumored “iWatch.”

The most recent rumors indicate Apple could unveil an iPhone with both a 4.7-and 5.5-inch screen. Both sizes are pictured in the above mockup photo.

It is expected to be officially unveiled in September right along with iOS 8 itself.
