## Description

mu Barometer measures real-time air pressure using your phone’s built-in barometer sensor, tracks altitude, and analyzes pressure trends with precision. It offers a 48-hour pressure graph, supports multiple units (mBar, mmHg, inHg, atm) and altitude units (meters, feet), a status-bar pressure value, and an app widget for quick access.

Its hourly data collection enables offline use, and you can switch between pressure and altitude indicators by tapping the indicator. The app includes a widget with three themes and shows a live status-bar pressure value for quick reference; you can view relative altitude from your current point.

## Review summary

Users praise accurate readings, offline use with the device sensor, and rich customization (widgets, icons, displays, and a marker needle). The charts of past pressures and real-time data are highly valued, as is responsive support. Common drawbacks include high RAM usage, occasional data inaccuracy, and features that don’t work smoothly for some (location bugs, time axis offset, and paid widget/upgrade issues). Overall, a versatile barometer with strong features and usability, with attention needed for performance and reliability.

### Pros

- Accurate readings and the ability to calibrate the sensor to match local weather stations
- Works with the phone's built-in barometer and can operate offline without internet or location data
- Rich customization options, including widgets, icons, adjustable displays, units and scales, plus features like a marker needle
- Good data visualization: charts of past pressures, high/low values, and real-time measurements
- Responsive, helpful support and generally easy-to-use interface

### Cons

- High RAM usage / memory consumption
- Occasional inaccurate or bad data readings
- Location functionality issues (location not working)
- Time axis/time zone display discrepancies (time offset)
- Paid features or widget upgrade not functioning / purchase problems
