Barometer - Barometric Delta

Barometric Delta uses your device's built-in barometer sensor to monitor atmospheric pressure. Track live trends with a rate-of-change gauge, view history on graphs, and set custom threshold alerts to get notified when air pressure shifts. Ad-free and fully offline with a clean, minimal design.

Example Uses:
• Weather: Visualize local atmospheric changes through barometer shifts, and monitor incoming severe weather or storm fronts.
• Altimeter: Receive altitude ascent/descent notifications based entirely on hardware barometer sensor data (designed to save battery - no GPS tracking).
• Industrial: Test HVAC systems, building airtightness, and measure elevator speeds.
• Transportation: Travel with continuous monitoring of cabin pressure variations in vehicles, aircraft, and vessels.

Features:
• Pressure Gauge: View per-second changes in hectopascals/millibars (hPa/mbar) on a real-time dial, alongside per-minute trend calculation.
• Interactive Graphing: Analyze hyperlocal pressure history from 1 second up to 30 days to chart long-term atmospheric patterns.
• CSV Data Export: Save timestamped historical pressure data logs directly to a spreadsheet file (up to 1 year of data).
• Live Notifications: Display real-time hPa readings in the status bar and receive instant background notifications when custom thresholds are exceeded.
• Minimalist Utility: Includes light/dark themes and robust customizable gauge and graph ranges in a lightweight, battery-optimized package.

Notes:
• App requires a device with a barometric pressure sensor (if you are able to download this app from Google Play, your hardware has likely met this requirement).
• Readings can be affected by device HW, movement, case, waterproofing, or physical pressure.
• On Android 13+ you will be asked for notification permission to enable background pressure monitoring and alerts (depending on your device, you might also need to disable battery optimization for extended logs).
