About this app

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.
