Barometer – Pressure Alerts

Air pressure, plainly shown.

The current reading with a trend arrow, a 48-hour line — the last 24 hours observed, the next 24 forecast — and a neutral heads-up when a noticeable swing is coming.

• Uses your phone's barometer when it has one, and the local forecast either way
• 48-hour pressure graph with a clear now-line
• Change badges when the forecast moves 4 hPa or more in 12 hours
• Optional alerts: pick a threshold (4, 6 or 8 hPa) and get a local notification. Alerts are scheduled when you open the app.
• Location is optional: use approximate location, search a city, or type coordinates
• The last forecast is saved, so the app works offline
• Forecast data by Open-Meteo.com
