Navionics® Boating

Charts for time on the water

Navionics® Boating is a marine chart and trip-planning app for people who cruise, sail, fish or explore by boat. Made by Garmin, it brings nautical charts and lake maps to an Android phone, with chart areas available for offline use. That can be useful when you want to check a route or shoreline away from a reliable connection.

Read the water your way

Chart options include nautical information such as depth contours, navigation aids, ports and anchorages. SonarChart HD adds detailed underwater contours, which can help anglers assess likely fishing spots. Depending on the coverage, the app also offers government charts, relief shading, sonar imagery and satellite views. You can adjust chart layers and highlight shallow areas to suit the conditions or the task.

Plan, mark and review

For trip preparation, Auto Guidance+ can suggest a dock-to-dock route based on chart data and navigation aids. The app can show details such as distance and estimated arrival time. Weather forecasts, wind, tides and currents provide additional context before heading out. On the water, you can save markers, record tracks and measure distance between points, then use those records to look back at a day’s outing.

Useful context before you set off

Local knowledge is part of the package: boaters can view and contribute community information, including points of interest and recommendations. Chart coverage and available features vary by location, and continued access to charts and advanced tools may require a yearly subscription. With 5,000,000+ installs, the app has a broad audience; its 2.85 rating from 48,826 reviews is a reason to check whether its coverage and tools match your needs before relying on it for a trip.
