Reads local air pressure and computes altitude in real time using a device barometric sensor, presenting values in mBar, mmHg, or psi. Barometer - Air Pressure comes from Trajkovski Labs and sits in the measurement category, offering a vintage aneroid display alongside digital readouts. Key functions include an altimeter, vertical speed calculation, and automatic range detection. Outdoor users, pilots, and weather hobbyists get immediate, localized pressure data for planning and monitoring.

What the app measures and how it reports it

Barometer samples the phone's pressure sensor and reports atmospheric pressure and altitude continuously. Readings are available in mBar, mmHg, and psi, and the tool provides both an analog-style aneroid face and numeric output. The altimeter derives height from barometric pressure changes and offers an optional GPS/web elevation feed to refine estimates when enabled.

How accurate and local the measurements are

The app relies on the device's built-in pressure sensor to deliver real-time, localized data; when a hardware sensor is present the app functions offline. For devices without a sensor it uses meteorological station data from Yr.no as a fallback, so accuracy depends on proximity to that station rather than direct local measurements. Vertical speed and acceleration are computed from rapid pressure changes to report motion along the vertical axis.

Safety, permissions, and user interaction model

The app reads device sensors and uses optional location or web services only when the user enables those modes; barometer and altimeter functions work without internet if a sensor exists. The interface pairs a vintage visual dial with straightforward numeric fields, which reduces configuration steps. User reception notes the lack of complex settings and clear presentation, helping users who prefer immediate readings over extensive setup.

Recommended for sensor-equipped Android users who need on-device pressure data

Barometer suits hikers, pilots, and people tracking pressure-sensitive health events by delivering local readings when a device sensor is available. Expect more representative, device-level values with a built-in sensor; reliance on station data is a trade-off for sensor-free devices. For routine outdoor checks, confirm the app's altitude baseline before setting out. Recommended.
