METAR Master brings clarity to the sky.

One screen. Category, wind, risk — and the why behind all of it.

LIVE METAR · TAF · RISK

Read the sky in plain English.

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.

EVERYTHING DECODED

From raw code to a call you understand

Deterministic parsing, a transparent risk engine, and the raw report always one tap away. Never a black box.

Plain English, instantly

Every group of the report, translated the moment it loads — wind, visibility, ceiling, remarks and all.

“Winds are from the south at 20 knots gusting 28.”

Risk that shows its work

Low to Severe, scored from the facts in the report — and every contributing reason listed, every time.

RISK: MODERATE score 5
· Wind gusting to 28 kt (gust spread 8 kt).
· Sustained wind 20 kt.
· Your max gust is 25 kt. Current gusts are 28 kt.

TAF as a timeline

FM, TEMPO and PROB groups become color-coded blocks — with training notes when it matters.

FAQ

Good questions

Is this an official weather briefing?+

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.

Where does the weather data come from?+

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.

Does it work without a signal?+

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.

I'm a student pilot. Is this for me?+

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.

iPhone or Android?+

Both — METAR Master is coming to the App Store and Google Play. Leave your email above and we’ll tell you the moment it’s live. The web share links work in any browser today.
