Peakflow – Trail & Summit App

Peak Flow — the free outdoor route planner that really knows the mountains. Real trails, satellite snow, live webcams, voice navigation. No ads. No subscription. No premium.

🗺️ ROUTE PLANNING ON REAL TRAILS
Plan on marked hiking paths and singletrails with BRouter — no straight lines, only real trails. Distance, elevation gain and realistic time for every route. Drag waypoints or long-press to delete.

🛰️ SATELLITE SNOW
See from daily Sentinel-2 imagery (~10 m) where snow and old snowfields still lie up high. If your route crosses a snowfield, Peak Flow shows the snow map automatically and warns you — so you know beforehand whether you'll need crampons or an ice axe.

📹 LIVE WEBCAMS ALONG YOUR ROUTE (NEW)
One tap and you see every webcam along your tour at a glance, from start to finish. A live look at the summit before you even set off.

🌿 VEGETATION & AUTUMN COLOURS (NEW)
By satellite, see where it's lush green and where the slopes are already turning. Perfect for timing your most beautiful photo tours.

☀️ SUN & SHADE THROUGH THE DAY (NEW)
Where does the sun rise, where does it set — and where is there still shade at 1 p.m.? Plan your ascent in the shade and the summit in the sun.

🧭 NAVIGATION WITH VOICE GUIDANCE
Turn-by-turn prompts at junctions, warnings on steep sections, remaining time and distance in real time. The map rotates in your direction of travel — even offline.

🏔️ BERGKÖNIG – DEFEND YOUR TERRITORY
Collect peaks, passes and huts. Whoever visits a summit most often wears the crown. In every peak's info you see who currently holds it — become the Bergkönig yourself and defend your title.

📍 53,000+ PEAKS, HUTS & PASSES
Thousands of Alpine summits with SAC difficulty grade (T1–T6), elevation and description. Dangerous sections are coloured automatically right on the route.

🦌 WILDLIFE PROTECTION ZONES (NEW)
Does your route cross a protected area? Peak Flow lets you know — including the seasonal closure. For a respectful coexistence with nature.

🥾 SURFACE CHECK (NEW)
How much trail, gravel and asphalt awaits you? Peak Flow breaks down every route by surface.

⛰️ GRADIENT-COLOURED ELEVATION PROFILE
Colour-coded elevation profile — the steeper, the stronger the colour. Spot the tough climbs at a glance.
