Avycast
Avycast aggregates official avalanche bulletins from ~30 regional warning services across 21 countries โ Alps, Pyrenees, Scandinavia, North America, Japan, New Zealand, Argentina, Georgia โ into one normalized feed. Each forecast shows danger rating per elevation band (above/at/below treeline), avalanche problem types (wind slab, wet snow, persistent weak layer, etc.), and full narrative (highlights, activity comment, snowpack comment). Bulletins auto-translate into 6 languages (English, German, French, Italian, Spanish, Russian) via AI, so backcountry travelers get official-source data in their own language regardless of where they're touring. GPS-based nearest-region detection finds the right bulletin instantly; favorites and push notifications keep you updated when a region's forecast changes. Free tier covers core forecasts; Premium (โฌ1.99/mo or โฌ14.99/yr, 7-day trial) unlocks extras. Available on iOS and Android.

Avycast's answer:
Avycast pulls official avalanche bulletins straight from ~30 regional warning services (EAWS members plus US, Canada, Japan, New Zealand, Argentina, Georgia) instead of running its own forecast model โ so danger ratings stay authoritative, source-verified, per-elevation-band. AI then translates and normalizes every bulletin into 6 languages and fills in avalanche problem types when a provider's raw text doesn't tag them, so a traveler anywhere gets the same structured, readable format regardless of local provider's format or language.
Avycast's answer:
Backcountry skiers, splitboarders, ski tourers, and mountaineers who travel across regions/countries and need official avalanche danger info without hunting down each country's own bulletin site/app.
Avycast's answer:
Most avalanche apps cover one region or country. Avycast covers 21 countries under one interface, auto-translated, with consistent elevation-band danger ratings and problem tagging across all of them โ no need for separate apps per mountain range. Free tier covers the core forecast; Premium is โฌ1.99/mo.
