Nostos

Nostos is a clean, practical companion for planning and sailing your trips in Greek and Mediterranean waters.

PLAN
• Tap the map to build a route with waypoints and anchorages
• Live distance, estimated time and trip duration (days/nights)
• Sea depths from open data (EMODnet) + seamarks (OpenSeaMap)
• Weather, wind and wave forecasts at each stop (Open-Meteo)
• Restaurants, beaches and sights along the way (offline database)
• Land-crossing warnings so a leg never cuts across an island

NAVIGATE
• Live position, heading (course-up) and speed
• Course line projected ahead + course-over-ground in degrees
• Next-waypoint ETA computed from your live speed
• Manual re-centre — pan freely, tap to return

DEPTHS
• Automatic depth readings when zoomed in
• Long-press anywhere for an estimated depth
• Optional: read real live depth from your boat's NMEA sounder over WiFi

MORE
• Save trips, calendar, cloud sync (optional sign-in)
• Downloadable region packs across the Mediterranean
• Greek/English, light/dark theme, metric/imperial units

Depth data from open sources is an estimate, not an official survey — always navigate prudently.
