One screen. Category, wind, risk — and the why behind all of it.
Live METARs and TAFs decoded into words you can act on — with a risk engine that always shows its work. Built for student pilots, and the pilots they become.
Deterministic parsing, a transparent risk engine, and the raw report always one tap away. Never a black box.
Every group of the report, translated the moment it loads — wind, visibility, ceiling, remarks and all.
Low to Severe, scored from the facts in the report — and every contributing reason listed, every time.
FM, TEMPO and PROB groups become color-coded blocks — with training notes when it matters.

Flight categories across the country — radar, IR satellite, SIGMETs and airspace, color-coded.

Tap any group in the raw report to see exactly what it means.
Every reporting airport in your corridor, briefed.
Quizzes are built from the real, live METAR you just read — not canned examples. Earn XP, keep a streak, and climb from Weather Rookie to ready-for-anything.
Every feature is free, supported by a few ads. $1.99 a month makes them disappear.
No. METAR Master is for education, training and situational awareness only. It is not a substitute for an official weather briefing, flight service, or pilot judgment. Always verify weather with official sources before flight.
From the AviationWeather.gov Data API, fetched and cached by our servers. Report time, fetch time and age in minutes are always shown — a stale report is flagged, never presented as current.
The cockpit tools do: decode AWOS/ATIS weather you copied by ear, and compute crosswind and density altitude — fully offline. Live METARs and TAFs need a connection.
Especially for you. Every decode doubles as a lesson, quizzes are generated from real reports, and wrong answers always come with the why. Certificated pilots use it to stay sharp.
