What's New in Barometric Pressure

2.63

August 24, 2026

•Added a user configurable altitude uncertainty threshold so the app can reject MSL pressure calculations if altitude uncertainty is outside the threshold. This can help avoid bad data from affecting the MSL calculation (Pro only). •Added detailed altitude and Sea Level (MSL) Pressure panels to see details of the MSL calculation (Pro only).

I really appreciate you leaving a review. I work hard to make this the most useful barometer app out there and I use it myself so I'm constantly testing and reminding it. I'm glad to hear that you're finding it as useful as I do!

Joint Pain

I have arthritis. I have learned through this app that my pain is worse when the blue dots line up horizontally.

Wow thank you so much for your kind words! It's a labor of love, but hearing that people find my apps useful is really what keeps me going! Please reach out if there's anything I can do to improve your Barograph experience. Stay tuned for the next update which will include a Home Screen widget!

Works as described

I wrongly set it up so put in a very critical review but it was my fault for not reading the instructions .
You need to go into,settings and assign permissions .
The developer pointed this out and now it is effective and what I needed.
If you want to remove the Ad Banner there is a small payment but it does run without that .

FAQ

What does Barograph do?

Barograph uses your iPhone's built-in barometer to create real-time charts of atmospheric pressure. It allows you to view pressure trends, set alarms for specific pressure values, and log data. The app can also display your relative altitude and offers an optional feature to view sea-level adjusted pressure.

What are the key features of Barograph?

Key features include real-time atmospheric pressure monitoring with dynamic graphs, customizable pressure alarms, background data logging, altitude display, push notifications for pressure changes, and the ability to export data in CSV format. An optional in-app purchase enables sea-level adjusted pressure readings.

Is Barograph free to use?

The app is free to download and use for basic features like real-time pressure monitoring and logging. However, advanced features such as sea-level adjusted pressure calculations require an optional in-app purchase.

What devices is Barograph compatible with?

Barograph is designed for iPhone and iPad devices that have a built-in barometer. It utilizes the device's hardware to provide accurate atmospheric pressure readings and charts.

How can I use Barograph for weather prediction or elevation tracking?

By monitoring pressure trends, you can anticipate weather changes, as dropping pressure often indicates approaching rain. The altitude display feature allows you to track elevation changes during activities like hiking or flying, as atmospheric pressure varies with altitude.
