About this app

On Trail is built for mountain people — from weekend hikers to seasoned ski tourers. It combines offline maps, AI-powered route planning, mountain weather forecasts and an outdoor community.

🤖 AI ASSISTANT — CHATAI
Talk to AI about mountains. Ask by voice or text:
• "Plan a route from Kuźnice to Kasprowy Wierch"
• "What's the weather tomorrow on Rysy?"
• "Which peaks in the Tatras haven't I visited yet?"
• "What's interesting near the mountain hut?"
ChatAI uses 24 specialized tools — plans routes, checks weather, trail conditions, avalanche danger and much more. You can also send a photo and ask AI to identify the peak.
