About GeoSea: Navigation & Fishing
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. 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. 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. SEA LAYERS (Copernicus) • Water temperature (SST), chlorophyll and sea level. • Marine reserves, wrecks, seabed type, submarine cables, seagrass and military zones. GPS NAVIGATION • Instrument bar: speed, course, depth and wind, in large type. • 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. ROUTES AND PASSAGES • Create routes with waypoints and autorouting that avoids shallows and the coast. • Navigate a route point by point: distance, course, arrival and drift, with a voice call at each point. • Passage planner: the best departure time, plus arrival, wind and waves for each 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 • «Go out today?»: tells you in words whether it is a good day for a small boat. • 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. • Tools button: every map button in one tray. • Home screen widgets: tide, fishing, weather and solunar. • Available in Spanish, English, French, German, Italian and Portuguese.

What’s new
Version 5.0.1 · Updated October 22, 2026
Smoother, with no stutters. What we fixed: • Moving the chart feels lighter: the crosshair works out its reference without slowing the drag. • With many AIS vessels around, the chart is no longer redrawn in full with every message. • Coastline points are no longer repainted on every map movement. • Ports, rocks and beaches are no longer re-filtered every time you move the chart. • The coastline loads at startup without slowing the screen. • The cloud and rain forecast is prepared in the background without taking smoothness from the chart. • Auto-routing is calculated without blocking the screen. • Less work on every GPS fix, including while navigating. • Less battery: the «More» diagnostics only run while you are on that tab.
