Meteo

The barometer in your phone, made honest.

Live air pressure from your phone's own sensor, the 3-hour trend that forecasters use, a sea-level estimate with its error bars, and a pressure map with isobars to put your reading in context.

Meteo's aviation-style pressure gauge

Two real instruments

A mercury barometer and an aviation gauge, drawn from the live sensor value. The number is the raw reading.

The weather trend

Rising, falling or steady over 3 hours, in the Met Office's bands, with a chart of your own history.

Sea-level pressure, with ±

Measure your height by GPS or enter it, and see the sea-level estimate next to what the sensor reads.

Pressure map

Isobars, highs and lows from a forecast model, nearby airport reports, and your reading on top, 3 hours back to 24 ahead.

Check your barometer

Compares your phone with nearby airports so you know how far off its sensor is. Shown, never silently applied.

Private by design

No account, no ads, no tracking. Readings stay on your phone; everything but the map works offline.

Honest data. Meteo shows only real measurements. Phone pressure is pressure where you are (station pressure); the sea-level figure is always labelled an estimate with its uncertainty. Height changes (lifts, hills, cars) are detected and shown, not hidden. Model data on the map is labelled as model output.
