Mountain Safety

Know the mountain
before you clip in.

Weather, avalanche bulletins, snow quality, and terrain analysis for your favorite resorts — one calm view of the conditions that actually matter, with offline maps for when the signal doesn't reach the mountain.

Everything you'd check before a ski day, in one place.

No more switching between five apps and a bookmarked PDF. First Chair pulls the signals that matter into cards you can actually act on.

Avalanche level, snow quality score, terrain overlays, and run statistics as tappable cards
Resort dashboard

Tap into the cards that matter.

Avalanche danger, snow quality, terrain overlays, live radar, and run statistics — all live on the resort page, all one tap from the full detail.

3D terrain view showing a steepness-colored analysis line down the mountain
3D terrain

Inspect terrain as a 3D line.

Sweep a fixed analysis path down real terrain and see exactly where it steepens — steepness, aspect, and elevation, read off a line instead of guessed from a flat map.

2D map colored by avalanche-relevant slope angle bands
Terrain-aware maps

Read steep terrain right on the map.

Switch the basemap into classic slope shading or avalanche terrain classes, so the angle of what you're looking at is visible while you're still planning the line — not just after you're on it.

Snow quality score of 25 out of 100, with a transparent breakdown of what raised and lowered it
Snow quality

See how the surface is shaping up — and why.

A single score combining fresh snow, freezing level, wind, sun exposure, and the current avalanche bulletin. Nothing is hidden: every score shows exactly what raised or capped it.

"Raw surface score 75 was capped to 25 by the safety gate" — the avalanche bulletin always has the final word, even when the snow itself looks great.
Weather radar nowcast over Hintertux with an hourly scrubber
Nowcast radar

Check what's moving in, now.

Scrub through the last few hours and the next few to come — useful the moment the sky starts looking uncertain, not just first thing in the morning.

Mountain weather forecast broken down by elevation band, valley to peak
Mountain weather

Read the day by elevation.

Valley and peak rarely agree. Compare temperature, wind, and precipitation across the elevation band you'll actually be riding, hour by hour.

Built around the decisions that count.

First Chair isn't trying to be a game or a social feed. It's a planning tool for the fifteen minutes before you leave the hotel room.

Real avalanche bulletins

Official regional danger ratings and problem types — not a guess, the actual published bulletin for where you're headed.

Download it before you go

Elevation, basemaps, runs, lifts, and terrain overlays all cache offline — resort Wi-Fi and mountain signal are not a given.

No black-box scores

Every rating — snow quality, terrain risk — shows its inputs and the exact rule that capped it. You can always see why.
