Metar USA vs FD Viewer

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your station plus the ten closest to you, ranked by distance • The observation time is highlighted when the report is no longer current • No account, no advertising, no data collected Data comes from the Aviation Weather Center (NOAA), exactly as published at the source.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.

Area Forecast Discussions (AFDs) are a text weather product released by the National Weather Service (NWS) Weather Forecast Offices to inform and elaborate on the public forecast. FD Viewer presents each office on a map and also displays a list of offices sorted by distance or alphabetically. Selecting an office will display the latest Forecast Discussion paginated by section. Swipe right or left to navigate through each section. This app merely reformats the web-based AFD information in a user-friendly format. All credit for the forecast information goes to all the hardworking people at the NWS. TBD: I plan to support in-app glossary popups that will describe some of the more arcane acronyms and phrases used in the forecast text.
