We've created the ultimate Barometer & Barograph Application for your iPhone 6, iPhone 6 Plus or iPad Air 2. (NOTE: Only works with these devices, as other devices don't have a barometric sensor)

Easily read the value of the internal atmospheric pressure sensor, and view the relative changes in a simple graph. With live, daily, weekly and monthly charts. Rotate your device to get a fullscreen graph!

The app also includes a widget, so all you have to do to view the current air pressure is swiping down to reveal the notification center!

Choose between these atmospheric pressure units:
- Hectopascal (hPa), equal to milibar (mbar)
- Milimeter of mercury (mmHg), equal to Torr
- Inch of mercury (inHg)
- Pounds per square inch (psi)
- Standard atmosphere (atm)

The GPS altitude is used to adjust the dial display and to show the normal air pressure for your current altitude!
