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.

Barometer Plus app measures air pressure and altitude using your device's built-in barometric pressure sensor. Because air pressure changes usually indicate a weather change, you can use this app to monitor and predict short-term weather variations. People suffering from migraine, headaches, or joint pain can monitor how barometric pressure impacts their mood. Fishermen can monitor the atmospheric pressure for right-time fishing. FEATURES: • The app contains a barometer and altimeter with a personalization graphic in classic analog style. It also displays the current temperature and humidity. • Display barometric pressure (sensor value) or mean sea level pressure (MSLP - value used in weather forecast services or stations). • Units support for pressure: mb, inHg, kPa, atm, Torr, psi, hPa, mmHg. Units for altitude: meter, feet. • Calibrate the barometer using altitude/location from the GPS. Calibrate the altimeter using the nearest airport information/METAR, or manually enter the QNH of the nearest airport. Offset sensor output value. • Measure the height (building/mountain/hiked/climbed) using the "Relative Altitude" feature (can be enabled in the app's Settings). • Notification about pressure change. "Notification custom rule" for you to define how and when the app sends notifications. Notify when air pressure changes indicate that extreme or worse weather may occur. • "Pressure Tracking" and "History Graph" require "Background App Refresh" or "Always Location Service" with "Exact update interval" enabled. • "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data. • Export history to CSV format and Today widget. • This app is the digital version compared with an aneroid or mercury barometer and can be adjusted to MSLP with additional features. CUSTOMIZABLE: You can change your barometer/altimeter appearance with: • Seven different housing colors. • Black, white or blue disk background. • Four different app backgrounds. • Three different types of needles. • Marker needle for easily monitor. • Dark or light Today widget theme. NOTES: • App only works on devices with a barometer sensor, such as iPhone 6/6s/7/8/X/11/12/13 (including Plus models), iPad Mini 4/Air 2/Pro, or later. • Weather icons on the dial: This only shows the air pressure trend like in an analog barometer. • Each time your device reboots, open the app for tracking with the "Exact update interval" feature work. • You may take the phone/tablet far away from computers, cables, and other magnetic sources to get accurate results. • This app is Pro / Premium version of the "Barometer Plus - Altimeter" app, only difference is all feature unlocked and no ads. If you already use the "Barometer Plus - Altimeter" app and purchased in-app, do not need to purchase this again.
