i-Boating:Marine Navigation

Marine navigation just got smarter. i-Boating:Marine Navigation is the #1 marine charts app that transforms your phone into a professional-grade boat chartplotter, complete with offline nautical charts, inland river maps, and lake depth contours — all without needing an internet connection once downloaded.

Navigate with confidence using GPU-accelerated NOAA and ENC (Electronic Navigation Charts) that keep text upright and readable at any orientation. Access HD 1-foot and 3-foot bathymetry contours for over 75,000 lakes across North America, plus seamlessly stitched coastal, approach, harbor, and inland charts covering the USA, Canada, UK, Ireland, Australia, Mediterranean, Caribbean, and beyond. Whether you're crossing open water or threading through narrow channels, you have the most comprehensive chart coverage available — a superset of Navionics, C-Map, Lowrance, and other leading navigation systems.

Create and manage boat routes with pinpoint accuracy. Set waypoints, import GPX and KML files from your existing trip plans, and let the app guide you step-by-step with real-time voice prompts. Know exactly when you're approaching a marker, your distance to destination, estimated time of arrival, and whether you've drifted off course. The anchor alarm keeps you safe if your boat moves unexpectedly, while auto-follow mode overlays your real-time position and predicted path on the chart.

Fishing enthusiasts gain an exclusive edge with AI-powered fishing hot-spot detection and lake temperature maps showing thermocline layers down to 0.5°C precision. Identify structure, find where fish congregate, and troll more effectively with professional-level depth intelligence. Maritime aids — beacons, buoys, marinas, boat ramps, and fishing attractors — are all clearly marked.

Stay informed with integrated tide and current predictions, wind forecasts (GFS and ECMWF models), marine AIS tracking for nearby vessels, and NMEA support for external instruments like sonar and water-temperature sensors. Record your actual tracks, review your journey, and export logs for your boating records.

Unlimited chart updates for one full year keep your navigation data current. Whether you pilot a fishing boat, sailboat, or cruiser, i-Boating:Marine Navigation delivers the reliability and detail of a dedicated marine electronics system in your pocket.
