## What is LacNav?

Navigate Swiss lakes like a local.

LacNav knows every shore zone, every speed restriction, and every named wind — so you can focus on the water, not the rules. Built exclusively for Swiss waters. Not adapted from an ocean app.

SHORE ZONES & SPEED ALERTS
Real-time audible alerts before you enter a restricted zone or exceed the speed limit. Stay legal without watching the screen.

LAKE CONDITIONS AT A GLANCE
Live wind, gusts, water temperature, wave height, UV index and lightning alerts — everything a skipper needs before leaving the dock.

WIND, RAIN & CURRENT OVERLAYS
See the Bise building on the Zürichsee before you cast off. Named winds — Bise, Foehn, Séchard, Tramontane — identified and displayed directly on your chart.

DYNAMIC SPORT SPOTS
Stop guessing. LacNav reads live conditions and tells you exactly where and when the water is perfect for wakesurf and sailing.

FUEL, MARINA, RESTAURANT. ALL ON THE MAP.
Every fuel station, marina, boat ramp, ferry terminal, restaurant and public facility on all 8 lakes — one tap away.

8 SWISS LAKES
Zürichsee · Lac Léman · Bodensee · Vierwaldstättersee · Thunersee · Brienzersee · Lago Maggiore · Lago di Lugano

OFFLINE MAPS
Download your lake once. Navigate without mobile signal — maps, zones, POI and weather cache all stored on device.

ONE-TIME PURCHASE. NO SUBSCRIPTION. EVER.
Buy once. Use every summer. No annual fees, no paywalls, no surprises.

Available in English, Deutsch, Français, Italiano.
