Built for the mountain, not the weather app.

Every number in Slab comes from a model, a forecaster or the map, and Slab tells you which.

Snow forecast

Six weather models blended into one number, at the top, middle and base of every resort, with how far the models disagree.

Snow on the mountain

Play the next days of snowfall across a 3D model of the mountain and see which slopes it lands on.

Avalanche bulletin

Danger by elevation and the problems to watch for, from the official forecasters in 284 regions across Europe and North America.

Slope angle and terrain

Slopes of 30° to 40° and steeper, plus avalanche start zones and run-outs, painted on the map.

Piste maps

3,500 resorts with every lift and piste, its grade, length and vertical, on a 3D map you can turn.

Webcams and radar

Live webcams from the resorts you follow, and snow radar to see the storm move in.

Record your day

Every run, lift, top speed, distance and vertical, recorded as you ride and kept on your phone.

Your mountains

Follow the resorts you ski and see fresh snow, the week ahead and the danger level at a glance.

In your language

English, German, French, Spanish, Japanese, Korean and Simplified Chinese.

Slab Pro

Ask for a line. Ride it.

Slab Pro plans your day on the mountain and guides you through it, run by run.

  • Ask the mountain in plain words, like “the steepest black run”, and Slab finds it on the map.
  • A day of runs planned for you, guided lift by lift, on your Lock Screen too.
  • Flake News, a snow report for your mountains, written from the weather models.
  • The 15-day forecast, unlimited resort search, and powder alerts on every mountain you follow.

Monthly, or a yearly Season Pass with a 7-day free trial. Planning and guidance are free on the first day you use them.

Slab helps you decide. It doesn’t decide for you. Forecasts and bulletins can be wrong, and terrain layers are a guide, not a guarantee. Slab doesn’t replace avalanche training, the right equipment, local knowledge or a mountain guide. Read the full bulletin from your local forecaster before you go off-piste.

See you at the first chair.
