First Chair: Mountain Safety

Find better snow. And stay safe.

First Chair brings the official avalanche bulletin, the terrain under your skis and the conditions at your resort onto your iPhone: live on your Lock Screen while you ride, in 3D for any slope you aim at, and on one page for every resort you love.

PROTECT MODE: YOUR AVALANCHE RISK, LIVE
Start Protect and First Chair follows your position. On the Lock Screen and in the Dynamic Island, without opening the app:
• What today's avalanche report says for your region and your altitude
• How steep your slope is compared with today's critical angle
• The avalanche problems that apply right where you stand

3D TERRAIN: AIM, SHOOT, ANALYZE
Point the aiming box at any slope and fire. First Chair builds the terrain in 3D and reads it for you.
• Avalanche terrain hatched in red, steepness and aspect for every point
• Swipe the lens: steepness, avalanche, cliffs, sun exposure, snow quality, wind and snowfall
• Plan anywhere on the map, with live stats under the crosshair

RESORT PAGES: YOUR RESORT, HOUR BY HOUR
• Mountain weather from valley to peak, hour by hour, in a 3D forecast
• Live webcams and weather stations on the 3D map
• A snow quality score that shows exactly what raised or capped it
• New-snow alerts for your favorite resorts

WORKS OFFLINE
Download a resort before you go. Elevation, basemap, runs, lifts and terrain layers stay on your phone, because mountain signal is not a given.

WHERE THE DATA COMES FROM
• Official avalanche bulletins: the EAWS warning services across the Alps, avalanche.org in the USA and Avalanche Canada
• Your phone's GPS
• Satellite elevation data (Copernicus DEM, SRTM)

ONE MORE LAYER, NOT A REPLACEMENT
First Chair is one more layer of information. It doesn't replace an avalanche course, your beacon, shovel and probe, what you observe, or your own judgment. Data can be wrong or out of date. You make the call, and you carry the risk.

First Chair Pro is an optional auto-renewing subscription (monthly or yearly). Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel it in your App Store account settings.
