Barograph is an app that uses the barometer in your iPhone 6 or iPhone 6 Plus to plot the atmospheric pressure in real time. Barograph can also collect barometric pressure values in the background using Background App Refresh. You can use this app to watch weather systems (dropping pressure generally means rain is coming), or to see how the pressure changes as you move up and down in elevation. Barograph also displays your relative altitude using the barometer data.

With Barograph you can:
•View a graph of the atmospheric pressure as it changes in real time in units of kPa, mbar, hPa, or inHg
•Record barometer data in the background using "Background App Refresh".
•Receive periodic push notifications with atmospheric pressure values and trends.
•Share barometer data over email, Facebook, Twitter, etc.
•Save and share images of your barograph plot.
•View your relative altitude using the barometer in meters or feet.

Barograph now contains a notification center "today view" widget which let's you quickly check the atmospheric pressure at any time by swiping down on your screen.

•Fixes an issue where certain units would be cut off on the top display.

Ratings and Reviews

Does not appear to work in background


No barograph apps seem to work ing background, but this one claims it does. Nope.

Developer Response

It actually does work in the background, using Apple's background app refresh API. If you'd like help getting that feature set up, please contact me via email.

I love my iPhone 7 and I love this app


The latest iPhones contain an internal barometer that is incredibly sensitive--it has to be to detect very minor changes in positioning like sitting vs standing, in order to accurately generate all the fitness data.

This neat app unlocks that feature and displays the high-precision data in an intuitive, real-time plot. This is especially useful for weather geeks. You can even adjust the units to suit your fancy.

I love the new improvements to the graph; they make it much more useful in conveying the data. The sharing feature also allows me to email the graph and the underlying data in .csv format to import into a spreadsheet and do whatever I want with it. Finally, the notification and widget features really make this such a handy app.

Fun and Educational


When storms approach the pressure drops and with this app you can see it happening in realtime, or you can archive several weeks of data. The internal barometer is so sensitive it sees the pressure change just from walking upstairs, or even a wind gust hitting your house. Climb a hill and track the altitude change, or watch the cabin pressure change when you fly on an airline. Highly recommended as a teaching tool for your kids or just learning basic high school physics.
