Open the mapAny resort, at a glance
Tap a pin. Temperature, wind up top and snow on the ground, then when the snow is coming, day by day.
Every resort gets a card: what's on the ground, what's coming day by day, and the avalanche danger.
Mt. Bachelor, 15 Mar 2025, replayed in the real app with that day's data.
Who has the best snow?
Check at a glance. Every resort's pin is coloured by its snow, from grey to the rarest orange: fresh snow, the week ahead, the season and more.
Coming this winter
Snow score
One number from 0 to 100 for today and the next three days: fresh snow, how light it is, wind and warmth, weighed together. The best day stands out, and the map can colour every pin by it.
Mt. Bachelor, 13 Jan 2024 (replayed): 86, powder, third in the West that day. Snow score is still being checked against real storms.
Every layer, past and future
Past layers show what fell, future layers what's coming. Press play on any of them.
Every card also carries the local avalanche centre's danger rating once forecasts start for the season.

Our promise
Weather apps have a habit of taking things away once you rely on them. We're writing down now what we will never do, and we'll keep it.
-
Free stays free
Free forever: the past and present everywhere (radar, snow that fell, snow on the ground, every resort card with its full 7-day snow numbers, avalanche danger).
-
Premium adds more features and layers
Premium gives you the forecast maps past tomorrow and our deeper reads of the week ahead. From launch day, nothing free moves to paid.
-
Small ads, never in the way
The free app and site carry one small banner, never over the map controls or a resort card. No pop-ups, no full-screen or video ads, ever, and premium has none. There are no ads yet: the banner arrives with the store apps and 1.0, and we'll say so here first.
