Hawaii Ocean Map brings professional-grade seafloor mapping to your iPhone and iPad. Explore the depths around the Hawaiian Islands with NOAA's high-resolution bathymetry data—all available offline, with no subscription required. PROFESSIONAL DEPTH DATA Access detailed ocean floor topography derived from NOAA's Continuously Updated Digital Elevation Model (CUDEM) at approximately 3-meter resolution. Find underwater features including reefs, ledges, channels, and drop-offs with precision. WORKS OFFLINE Download maps before you head out. Whether you're miles offshore or in areas with no cell coverage, your depth data is always available. Perfect for ocean adventures beyond the reach of cellular networks. INSTANT DEPTH QUERIES Tap anywhere on the map to instantly see the water depth at that location. Plan routes, identify fishing spots, or explore underwater terrain with a simple touch. SAVE LOCATIONS Mark and save your favorite spots with custom placemarks. Add names, notes, and organize your locations for quick reference on future trips. NAVIGATE TO WAYPOINTS Select any saved placemark and get live bearing, distance, and a compass guiding you to your destination. Keep your eyes on the water while the app points the way. RECORD GPS TRACKS Capture your routes as you explore Hawaii's waters. Start, pause, and resume recording, then export your tracks as standard GPX files to share or analyze. Your tracks sync automatically across all your devices via iCloud. MAP LAYERS Toggle and explore ocean overlays from one dedicated page—fishing restriction zones, ORMA ocean recreation areas, humpback whale sanctuary boundaries, submarine cables, and curated points of interest including harbors, boat ramps, FAD buoys, surf spots, dive spots, and lifeguard towers. Zoom directly to any layer on the map. IMPORT YOUR SPOTS Bring years of accumulated spots with you. Import KML, KMZ, and GPX files—exports from Google Earth, Navionics, Garmin, and most chartplotters and fishing apps—and each file becomes its own map layer of points, lines, and areas. Rename, show, or hide every layer, tap any feature for details, and your imported layers sync across all your devices via iCloud.
