A METAR (Meteorological Aerodrome Report) is a standardized weather observation issued by airports worldwide, typically every hour. It encodes current conditions like wind speed and direction, visibility, cloud cover, temperature, dewpoint, and barometric pressure into a compact text format. Minimums decodes these reports so you can read them at a glance instead of parsing raw text.

Head to Settings > Personal Minimums to configure your thresholds for ceiling, visibility, wind, and crosswind. If it's your first time, you can also use Guided Setup from the home screen. It walks you through each parameter step by step and recommends sensible starting values based on your certificate level.

All weather data is sourced from aviationweather.gov, a public API operated by the National Weather Service and the FAA. Minimums fetches observations directly from this service so you always get official, unmodified reports.

Not all stations report continuously. Some airports only issue METARs during operating hours, and automated stations can occasionally go offline. Check the freshness timer on each observation. If it's more than 60-90 minutes old, the station may have stopped reporting. Try pulling to refresh, or check a nearby airport.

Minimums currently supports airports within the contiguous United States (CONUS). We're exploring international coverage for a future update, but for now the app is optimized for US stations and data sources.

Yes. Everything (your personal minimums, saved airports, and preferences) is stored locally on your device. The app does not collect analytics, does not use trackers, and does not share data with third parties. Read our full Privacy Policy for details.

Minimums has no in-app purchases, no subscriptions, and no ads. We built it because we wanted a better way to check weather before a flight.

We'd love to hear from you. Send us an email at [email protected] with a description of what you experienced or what you'd like to see. Screenshots and your device model are always helpful for bug reports.
