Stop jumping between five apps to plan one mountain day.
Avalanche bulletin, weather, route beta, avalanche data, and routing: everything in one place.
Aggregated data from





Avalanche bulletin, mountain weather, route beta, trip reports, huts, ski lifts, and avalanche observations on the same IGN map. No need to open five tabs anymore.
Draw on the IGN map or let the routing engine do it for you. The community track heatmap shows where people actually go. GPX import and export included.
Connect Strava and ChatGPX analyzes your history: vertical gain, route grades, and mountain ranges to build your profile. The AI adapts to your real experience, not a self-declared level.
Ask questions as if you were talking to a mountain partner. The AI checks live data, cites sources, remembers your preferences, and lets you tune its personality.
IGN basemap with 3D view, colored slope overlay, aspects, community heatmap, and ski lifts. Stack the layers you need to read the terrain at a glance.


The avalanche bulletin opens directly on the map, together with geolocated observations and altitude-based weather. All data comes from public sources including Météo-France, IGN, Camptocamp, and Skitour, and stays traceable.
Routing mode shows the community track heatmap. Drop waypoints and let the engine compute the best route. Switch to manual drawing for off-trail sections. Distance, elevation gain, and estimated time update live.


Ask in natural language. The AI checks the data, suggests routes that match your level, and displays them directly on the map. It can also help you debrief after the day.
The data and the AI automatically adapt to the season.
