Barometric Pressure: Barograph2.66 - App Store

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.

Version History •Improved debug logging when recovering from a crash - you can now export diagnostic files and send them to me for support.
•Improved notification formatting. 2.66 Sep 27 iOS 27 compatibility update 2.65 Sep 14 Fixed a rare crash that could cause a background refresh to fail 2.64 Sep 10 •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). 2.63 Aug 24 Improved the message that is displayed when a user does not have the proper privacy settings to access barometer data. 2.62 Aug 16 •Instead of using relative altitude (an older API) Barograph now uses absolute altitude as long as you have an iPhone 12 or newer. The absolute altitude is also used in the sea level pressure (MSL) calculation which is much more accurate than the older method of estimating location your map location based altitude.
•Further improvements of the retry timing for weather data request used in the sea-level pressure calculations
•Refinement of the background process when sea-level pressure is active. 2.61 Aug 14 Adjusted the retry timing for the weather data request used in the sea-level pressure calculation. 2.60 Aug 11 Added a recovery mode at startup for the unlikely event of database corruption issues. 2.59 Aug 11 Fix for a chart related crash bug and a potential startup hang. 2.58 Aug 9 Adjusted the elevation tracking algorithm used by the sea level pressure calculation (pro feature). 2.57 Aug 4 •Improved the sea-level pressure calculation feature - Barograph is now smarter about how it uses weather data and additional information is supplied about how the weather data is being used in the sea level calculation.
•You can now export your preferred units to CSV instead of defaulting to native units when exporting 2.56 Jul 28 Localization and Settings text format improvements 2.55 Jul 8 Maintenance release 2.54 Jun 27 Maintenance release 2.53 Jun 23 •Improved onboarding for new users
•Improved in app purchase process 2.52 Jun 7 Added a 24-hour pressure view. Now you can view all-time, 48-hour or 24-hour data on the chart. 2.51 Jun 2 •Added a fixed offset option in settings. This will not affect the saved data, only the chart display.
•Added better error reporting when there's and data or Motion & Fitness is disabled.
•Improved the data storage system and optimized performance by downsampling when there's too much data on screen at once. This does not affect saved data - only the data displayed on screen. You can always export all raw data to CSV. 2.50 May 25 Improved the layout for users with very large accessibility dynamic text sizes enabled. 2.49 May 15 Minor bug fixes and improvements 2.48 May 11 •Barograph now includes a Home Screen widget which shows the last 24 hours of pressure observations in a small summary chart.
•Added a background refresh log viewer to assist with troubleshooting background functionality. 2.47 May 7 Added a localization for Taiwan and minor language fixes. 2.46 Apr 24 The chart now follows the user's preferred date format. 2.45 Apr 14 •Made some of the colors more legible in light-mode. 2.44 Apr 12 •Added Japanese localization 2.43 Apr 9 •Number format is now localized - so all users will now see their preferred number format rather than only North American style numbers.
•Localization fixes for French, German, and Spanish. 2.42 Apr 7
