Meteo: Barometer & Weather Map
Turns your phone's pressure sensor into a working barometer. It shows the live reading on a mercury column or an aviation-style dial, records it over time and gives you the 3-hour trend that forecasters use. It also estimates sea-level pressure from your height and places you on a map of isobars. Readings are always labelled for what they are: your sensor, an airport report or model output.
Features
- Two live instruments: a mercury barometer and an aviation-style gauge
- 3-hour pressure tendency in Met Office bands, with history from 3 hours to 90 days
- Optional background recording about every 15 minutes, always with a visible notification
- Sea-level pressure estimate with its uncertainty, from GPS-measured or entered height
- Pressure map with isobars, highs and lows, airport reports and a forecast slider from 3 hours ago to 24 hours ahead
- Barometer check: compares your sensor with nearby airports and shows the offset without hiding it
- Lift and hill detection, so a change in height isn't mistaken for weather
- No barometer? Shows nearby airports' pressure, clearly labelled as an internet reading
Permissions
What the app asks for, and why.
| Precise location | Only when you tap Measure, to find your height above sea level by GPS. Only the height and its accuracy are saved, on the phone; coordinates are never stored or sent. |
|---|---|
| Approximate location | For the optional pressure map and nearby-airports reading. Your position is rounded to about 100 km before any request leaves the phone. Never used in the background. |
| Notifications & foreground service | For optional background recording. Android shows a notification the whole time it is on, with a one-tap Stop. |
| Run at startup | Resumes background recording after a reboot, only if you turned it on. |
| Internet | Only for the map and the airports reading: public weather data from Open-Meteo and aviationweather.gov, and map tiles from OpenFreeMap. Your readings are never sent. |

Help & troubleshooting
My reading is different from the weather report.
Weather reports give pressure reduced to sea level, while your phone measures the pressure where you are. Set your height (Measure with GPS, or type it in) to see the sea-level estimate. Phone sensors are also often a few hPa off; the barometer check on the map compares yours with nearby airports and shows the offset.
The pressure jumped suddenly.
A change in height does that: about 1 hPa for every 8 metres, so a lift, a hill or a drive is enough. Meteo marks these jumps on the chart so you don't mistake them for weather.
Why does the trend say "provisional"?
The tendency needs 3 hours of readings. Until there are enough, it's marked provisional. Turn on background recording to build up history even when the app is closed.
Background recording stopped.
Some phones stop background work to save battery. In Android settings → Apps → Meteo → Battery, allow unrestricted use, then turn recording on again in the app.
My phone has no barometer. Can I still use it?
Yes. Meteo shows the pressure reported by the nearest airports for your location, marked as an internet reading. The live instruments, recording and barometer check need a pressure sensor, which most mid- and high-end Android phones have.
Does Meteo collect anything about me?
No. There's no account, no analytics and no ads. Readings and history stay on the phone, and the map only ever sends a rounded area, never your position.
