About
Metar USA brings you the METAR observations of more than two thousand reporting stations across the United States, read straight from the official Aviation Weather Center (NOAA) source. The app opens on the full station list with the raw report, the observation time in UTC and the ICAO identifier coloured by flight category: green VFR, blue MVFR, red IFR, purple LIFR. One glance tells you where you can fly. Tap a station and the report is decoded item by item: temperature and dewpoint, wind direction and speed with gusts, visibility, altimeter setting in inches of mercury and hectopascals, field elevation and cloud layers in METAR notation. • Every US reporting station, refreshed on launch and on pull to refresh • Search by ICAO identifier • Map of all stations — tap a pin to read the report • Home Screen widget for the station you choose, in three sizes • Apple Watch app: your station plus the ten closest to you, ranked by distance • The observation time is highlighted when the report is no longer current • No account, no advertising, no data collected Data comes from the Aviation Weather Center (NOAA), exactly as published at the source. Metar USA is a quick reference tool: always rely on official sources and the required aeronautical documentation for flight planning.
What's new · 1.5
The weather service the app relied on was retired, and reports had stopped updating. This version moves to the current Aviation Weather Center interfaces: observations from more than 2,500 US stations work again. • Station identifier coloured by flight category: green VFR, blue MVFR, red IFR, purple LIFR • Observation time in UTC, highlighted when the report is no longer current • Altimeter setting shown in both inches of mercury and hectopascals • Cloud layers on a single line in METAR notation (e.g. SCT016 BKN033 BKN140) • Search by ICAO identifier or by the text of the report • Pull down to refresh • Rebuilt widget: refreshes reliably and now comes in the large size too • On Apple Watch the picker puts the ten closest stations at the top with their distance — no more scrolling an alphabetical list of thousands of airports • When data cannot be loaded the app explains why instead of showing an empty screen • Fixed a few widget crashes
