What's live today
Six core modules covering every step of pre-trip planning.
AI Trail Brief (8 seconds)
Pick destination + difficulty, tap Generate — get distance, cumulative elevation, 7-day weather, season risk, and a body-match note in under 8s. LLM timeout auto-falls to a preset brief; no blank screen.
Risk Grade Loop (our differentiator)
A single A–E grade backed by a tap-open 3-step reasoning chain: ① 7-day weather ② elevation vs your personal max ③ incident history match. Novice profiles auto-step up. Ignore is logged; re-warns on the next high grade.
Offline Tile Pack
One-tap download of ±10 km Mapbox tiles around your destination. Map, route, and cached Q&A all work in airplane mode. 1 pack free, 5+ on Pro.
Post-Trail DNA
Rate the trail across 5 dimensions after you return. The next AI brief uses your DNA history to tighten the fitness and style match. Reminders cap at once per 14 days.
