Features & Capabilities

Barograph uses the barometer built into your iPhone to draw realtime charts of the atmospheric pressure. It lets you view pressure trends, set alarms, and get alerts when the pressure changes. It also lets you log and export data to CSV format.

Discover the ultimate tool for tracking atmospheric pressure with Barograph, the original barometer data logger app designed specifically for iPhone and iPad. Whether you’re a weather enthusiast, an outdoor adventurer, or simply curious about atmospheric changes, Barograph offers powerful features to measure and analyze air pressure in real-time.

Key Features:

•Real-Time Atmospheric Pressure Monitoring: Instantly measure atmospheric pressure and watch dynamic graphs showing pressure changes over time. •Pressure alarms: Set an alarm and get notified when pressure rises above or below the desired value. •Background Data Logging: Use “Background App Refresh” to continuously collect barometric pressure data, even when the app is not actively in use. •Sea Level Adjusted Pressure: If you prefer to view calculated sea-level adjusted pressure instead of measured pressure, you can enable this feature with an optional in-app purchase. Adjusted pressure is calculated using your iPhone’s barometer and local weather data via Weatherkit. •Altitude Display: View your relative altitude based on barometer readings, perfect for tracking elevation changes during hikes or flights. •Push Notifications: Stay informed with periodic notifications that provide atmospheric pressure values, alarms, and trends, ensuring you’re always aware of significant changes. •Data Export: Easily share your barometer data in CSV format for further analysis or to share with friends and colleagues.

Use Cases:

•Weather Prediction: Track weather systems and anticipate changes. A dropping pressure generally indicates rain is approaching. •Elevation Tracking: Observe how atmospheric pressure changes with elevation, ideal for hikers, pilots, and outdoor enthusiasts. •Scientific Research: Gather detailed barometric pressure data for educational or research purposes, with seamless data export for comprehensive analysis. •Many people use atmospheric pressure data as an indicator of when they may have a migraine headache.

Download Barograph today and transform your iPhone or iPad into a sophisticated barometer data logger. Experience unparalleled accuracy and insight into the atmospheric pressure around you!

Maximize your understanding of weather patterns, elevation changes, and more with Barograph – your personal atmospheric pressure tracker and logger.

User Reviews

Summary: Users praise Barometer Graph for real-time, sensitive iPhone sensor data and ongoing development with a modern UI. The alarms and unit options plus cross-location trend tracking provide clear value for migraines, travel, and weather insights. Common drawbacks include unreliable background updates, privacy-permission friction in recent builds, ads despite purchase, lack of calibration controls, and inconsistent history/export behavior. Overall it’s a strong, feature-rich tool with caveats related to background operation and calibration.

Pros

Real-time, high-sensitivity pressure data from the iPhone barometer.
Active development and regular updates, including a modern UI (Liquid Glass).
Rich feature set: alarms, multiple units, and long-term trend viewing.
Practical value for migraines, travel, and elevation tracking.

Cons

Background data updates are unreliable, often requiring the app to be foregrounded to refresh data.
Recent updates require Motion & Fitness permissions, raising privacy concerns with no clear opt-out.
Ads persist after purchase / license not consistently recognized.
No calibration/offset controls for local pressure, reducing accuracy for some users.
History/plotting behavior is inconsistent (history not always shown; changing units can erase history; limited export/zoom).

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

I find it amazing that they’re still working on this app after so many years. I first tried it back in 2013 or 2014. It’s great to see a modern user interface and the new style of home screen which they recently added. The best thing about this app is it measures the pressure in the background. I don’t get data every minute of the day, but I get enough data points during the day that I always have an idea of the pressure trend and I can spot storms before they hit.
