Accurate Barometer PRO

Accurate Barometer PRO is a sophisticated Chrome extension featuring an elegant analog barometer dial that displays local atmospheric pressure alongside the pressure adjusted to mean sea level, the standard used by weather forecasts. Users also receive pressure data from the nearest airport and can visualize the latest 24-hour pressure trends via an interactive chart.

Designed for weather enthusiasts and those who rely on atmospheric pressure such as fishers, this extension allows calibration of the sensor, periodic automatic pressure recording, and supports multiple barometric units like hPa, mbar, mmHg, inHg, and psi. Note that devices without an integrated pressure sensor will only display pressure from the nearest airport, ensuring some level of data availability at all times.
