Monitor Atmospheric Pressure Accurately with a Streamlined Tool

Fluctuations in atmospheric pressure can impact health, planning, and daily comfort. mu Barometer provides a precise, ad-free instrument for real-time environmental monitoring directly from your device. It transforms your smartphone's built-in barometric sensor into a dedicated dashboard for pressure and altitude data, presented through a clean, customizable interface designed for utility and clarity.

The application functions as a primary data logger, capturing pressure readings hourly to build a detailed 48-hour history graph. It calculates altitude based on the current atmospheric pressure and offers a relative height measurement feature for tracking elevation changes from any starting point. Users can instantly toggle the main display between pressure and altitude readouts. The tool supports multiple units for pressure (mBar, mmHg, inHg, atm) and altitude (meters, feet), and delivers persistent access to data via a configurable home screen widget and a status bar notification.

Core Functionality and Features

mu Barometer operates as a dedicated environmental sensor hub, leveraging your device's hardware to deliver specific, actionable metrics.

• Display real-time atmospheric pressure in four selectable units: millibar, millimeters of mercury, inches of mercury, and standard atmospheres.
• Track and visualize pressure trends with a detailed, scrollable graph covering the past 48 hours of logged data.
• Calculate and display current altitude in meters or feet, derived from live barometric pressure measurements.
• Access key metrics instantly via a customizable home screen widget, available in three distinct visual themes.
• Enable a persistent status bar notification to monitor the current pressure value without opening the app.

The pressure graph is generated by a background service that records a data point each hour, creating a clear visual history for tracking storms or pressure fronts. Tapping the main display icon switches the central gauge between pressure and altitude readouts. For measuring elevation gain or drop, a tap on the altitude indicator sets a relative zero point, displaying the change from that reference.
