REAL TIDES More than 2,200 real tide gauges. «Negligible tide» where there is hardly any. DOWNLOADS THAT FINISH THEMSELVES If one is cut off, GeoSea completes it in the background. A LIMIT ALARM THAT DOESN'T GUESS Outside the limit only when your downloaded data proves it. NOAA CHART IN THE US, DARK MAP FIXED Satellite is now each country's official aerial imagery. TIDES AND FORECAST IN ENGLISH Tide table, Solunar, Fishing spots and forecast, no longer in Spanish.
Nautical charts, tides, AIS and GeoSea on your watch. Works offline too.
GeoSea is your nautical chart, your marine weather station and your fishing logbook, all in a single app. It works even without signal thanks to offline chart downloads. YOUR OWN DEPTH CHART Connect your boat's sounder (NMEA) and GeoSea records the real depth, corrected for tide, and draws it on your chart. If you want, it joins a chart shared by everyone: anonymous, never publishing a single reading or your track. NAUTICAL CHARTS • Official IHM charts (Spain) plus OpenSeaMap, EMODnet and GEBCO bathymetry. • Spain, Portugal, France, Italy, Germany, United Kingdom and a global mode to sail anywhere in the world. • Depths, navigation channels, buoys and marks, danger zones, contour lines and sea currents. • Download by area and navigate with no internet connection. SEA LAYERS (Copernicus) • Water temperature (SST), chlorophyll and sea level. • Marine reserves, wrecks, seabed type, submarine cables, seagrass and military zones. GPS NAVIGATION • Real-time position, heading, speed and depth sounder. • Centre cross showing depth, tide and data for the point under the cursor. • Compass, anchor-drag detector and spoken alert when you approach the coast. • Anti-grounding guardian and night-vision mode (red) for sailing after dark. • Tap any point on the chart to see its depth, tide and forecast, or plot a course to it. ROUTES AND PASSAGES • Create routes with waypoints and autorouting that avoids shallows and the coast. • Passage planner: it tells you the best departure time and the weather leg by leg. • Import and export routes in GPX (compatible with Navionics, OpenCPN and Garmin). • Record your trip, return along your own track, calculate fuel and plan under sail. MARINE WEATHER • Wind, wave, rain and tide forecast. • Hourly meteogram and cloud & rain radar. • Wind field on the map and storm & lightning risk alerts. • Tide tables by coordinate worldwide and a tide browser by port. FISHING • Best fishing times (solunar calendar) with a 7-day outlook. • Catch log with photos: species, weight, bait and geolocated notes. • Best-anchorage finder, sheltered from the wind according to the weather. SAFETY AND AIS • Live AIS vessels on the chart. • Collision alarm (CPA/TCPA): highlights ships on a collision course in red and warns you by voice. • Man Overboard (MOB): marks the position and guides you back with bearing, distance and time. • Alert when an AIS vessel comes closer than the distance you set, and an alarm panel you silence with one tap. AND MUCH MORE • Share your position live and follow other boaters in real time. • Fully customisable panels: reorder, show or hide the buttons you use. • Home screen widgets: tide, fishing, weather and solunar. • Available in Spanish, English, French, German, Italian and Portuguese. GEOSEA ON YOUR WATCH Speed, heading, tide and your chart — with your downloaded area and your favourites — at a glance on your wrist. Dragging alarm, Man Overboard and a tide dial that shows whether it is rising or falling. And with your boat's sounder (NMEA), GeoSea draws your own depth chart, corrected for tide. With no phone nearby it turns on its GPS, watches the anchor and has night vision. GeoSea is free to download.
