Rivers & Seas on iPad, iPhone, and Apple Watch with a map, bookmarks, and current boat data.

One map

OpenStreetMap and OpenSeaMap in a clear, modern app.

Your places

Return to anchorages, harbors, warnings, and discoveries.

Your boat

Course, speed, depth, and more directly on the map.

Try the map for yourself

Explore the waters where you spend your time.

Move and zoom the map just as you would in Rivers & Seas. Use the round map button to switch between the bright map, the automatic day-and-night map, Seascape with water depths, and satellite imagery. OpenSeaMap navigation marks remain visible in every view.

Nautical charts and water depths

From inland waterways to the coast.

Use OpenStreetMap on land and OpenSeaMap navigation marks on the water. Along the coast, Rivers & Seas adds depth shading, depth contours, and spot depths.

Switch at any time between a calm everyday map and the coastal map with water depths.

Ship radar and AIS

See nearby vessels directly on your map.

What is coming around the bend? What is the commercial vessel ahead called? How busy is the bay? The Rivers & Seas ship radar shows available live AIS traffic with names, direction and speed alongside your boating map.

Your route, local information and AIS stay in one app, with less searching and switching underway.

Places that matter to you

Your personal map grows with every trip.

Your bookmarks stay together across iPhone, iPad, Apple Watch, and later Mac.

Your boat data

Important values where you need them.

Rivers & Seas can display Signal K data from your onboard network, including course, speed, water depth, temperatures, and tank levels. With a compatible setup, you can even control the autopilot from iPhone, iPad, or Apple Watch.

Connect boat data with Signal K

Without a connection to your boat, Rivers & Seas remains a complete map and bookmark app.

If your iPad has no built-in GPS, Rivers & Seas can use the accurate position from your iPhone instead. Use your iPhone’s position on iPad
