Nimble Preflight
The professional pilot’s companion.
Weather, NOTAMs, hazards, route briefing and flight watch — in one fast, cockpit-dark app. Designed by an active airline captain, built on official sources, and engineered to keep working when the signal doesn’t.
Your route, your watchlist, and every hazard between them.
Great-circle track with embedded thunderstorm and icing zones, jet-stream cores and forecast timeline — scrub it to see what’s active at departure, en route, or on arrival.
One tab for every question a crew asks.
Weather, notices, hazards, charts, tracking and the calculators — each built for one job, all in one fast, offline-capable app that sits beside your official briefing, never replacing it.
One place for the whole pre-flight picture.
Weather, NOTAMs, advisories, charts, flight tracking and a full set of pilot calculators, gathered into a single fast app. The one you open in the crew room, on the bus, at the gate — everything a tap or two away, and most of it still working when the signal doesn’t.
Your airports, at a glance.
Up to a hundred stations, grouped by country. Each card shows the raw METAR, raw TAF and active NOTAM count without you opening anything — with an honest data-age indicator on top, so you always know how old the picture is.
One field, top to bottom.
Tap any card and land on one long scroll, always in the same order — a METAR trail with the newest tagged LATEST, the raw TAF, and a runway wind analysis. A speaker button reads the report aloud. Your eye learns the layout once and never hunts again.
Aerodrome and FIR notices — exactly as issued.
Split the way your briefing is: what affects the aerodrome, and what affects the airspace you’ll cross. Straight from the FAA Notice to Air Missions System and shown byte-for-byte — never reworded, never summarised.
Five families, five colours.
SIGMET, AIRMET, GAMET, volcanic ash and tropical cyclone — each family keeps one colour everywhere, on the chips, the cards and the map polygons. Filter to what matters, then view any hazard in its geographic context.
Observations, not forecasts.
AIREPs and PIREPs from crews actually in the conditions they describe. A chart tells you where turbulence is expected; a pilot report tells you an aircraft got it — at a time, a level and a position. The screen you check when forecast and reality might be diverging.
One route, five views, one pack.
Give it a departure, a destination and your alternates — Brief pulls the whole picture together into a single pack you can save and reuse.
One aircraft, followed properly.
Not a radar screen, not a fleet display — Flight Watch follows the one aircraft you actually need to know about: the inbound you’re taking over, the positioning flight that decides when your duty starts, the aircraft carrying your crew, a family arrival.
Progress on your lock screen.
Flight and percentage in the title, route and remaining time in the body — updated every minute, no need to reopen the app. And Flight Watch is the only feature that can send you a notification. Nothing else — not weather, not NOTAMs, not advisories — will ever interrupt you. While driving to the airport, you might just have time to grab a coffee on the way.
Five charts, five jobs.
Not variations on one picture — each tab answers a different question, and knowing which one to reach for is most of the skill.
SIGWX — the classic significant weather chart.
The WAFS high-level significant weather chart, covering FL250 to FL630 — the sheet every long-haul briefing pack contains. Jet streams, CB areas, turbulence boxes and tropopause heights, in a pinch-and-zoom chart viewer.
WIND / TEMP — upper winds at your level.
Wind barbs and temperatures for the selected region and flight level — the answer to “what should I expect at FL350?” before you ever read the OFP.
ECMWF RAIN — two days of precipitation, animated.
A precipitation-rate forecast from the ECMWF model, animated from now to T+48. Play it, drag the scrubber frame by frame, change speed — 0.5×, 1×, 2×, 4× — with the valid Zulu time on every frame and a SYNCED chip that tells you exactly how fresh the data is.
SATELLITE — the global infrared loop.
Colourised cloud-top temperature, worldwide, animated over recent frames on a pannable, zoomable basemap. Colder tops mean higher tops — you read it like a pilot, with the official DWD legend one tap away.
IWXXM SIGWX — significant weather as switchable layers.
The modern counterpart to the PNG chart: the same WAFS significant weather rendered as vector layers on an interactive map — CB, icing, turbulence, jet streams and tropopause, each a switchable pill, steppable from T+06 to T+48.
Ten calculators, one colour language.
The numbers you’d otherwise run on a phone calculator or the back of a jepp chart — each answering one question a line pilot actually asks, results saved straight to your repository.
And the rest of what a crew reaches for.
Whether you fly an airliner or a light aircraft — we all need a pilot companion.
Nimble Preflight might just be yours.
One price. Every tool. No tiers, no upsells. A 30-day free trial when we launch.
Early pilots keep the Founding Pilot price for good.
