Barometric Delta

About this app

Barometric Delta utilizes your device's built-in barometer sensor to monitor atmospheric pressure. Track per‑second and per‑minute pressure changes, and optionally receive notifications when pressure shifts beyond a custom threshold.

Example uses include measuring ascent/descent rates during flights, tracking elevator speeds, testing HVAC systems for drafts, and monitoring cabin pressure changes in cars and trains.

Features:
• Real‑time gauge: hPa per second (increase/decrease) with a simple dial.
• View trends: hPa per minute calculation to see short‑term rate of change.
• Pressure monitoring: optional notification showing live hPa readings.
• Custom alerts: set a pressure threshold and get notified instantly when exceeded.
• Fully offline: works entirely on-device hardware with no data connection.
• Simple controls and design: light/dark themes, adjustable gauge range, and the ability to hide some UI elements with a tap.

Notes:
• App requires a device with a barometric pressure sensor.
• Readings may be affected by device movement, case pressure, or physical force.
• On Android 13+ you may be asked for notification permission to enable background pressure monitoring and alerts.
