With Android smartphones and tablets becoming increasingly popular, a number of developers have now made available boat charting and navigational apps. Here we'll look at the first five Android apps that include marine charts and at least some functions for GPS navigation on the water:

  • MX Mariner
  • Memory-Map
  • Navionics Marine & Lakes
  • Marine Charts Lite and Marine Charts HD
  • NutiCharts Lite

This article provides an overview of each along with comparisons of key features.

For detailed reviews of each, links are provided below.

Choosing a Chart Navigation App

A boater's selection of a navigational app is ​a partly personal choice - but there are also objective differences in how apps work, what they do, and how well they do it. Following are specific factors to consider when selecting an app.

  • Obtaining charts for offline, on-water use. All charting apps include some method for downloading and storing charts for offline use because you never want to have to depend on connectivity when boating. In most cases, charts are included free with the app, but you still need to get them. And you need to be sure that you have every area you might possibly need, and in sufficient detail.

  • Type of chart: raster vs. vector. Raster charts are electronic versions of paper charts, with exactly the same information. Vector charts have a simplified graphic display that allows for greater compression and smaller amounts of storage used on the device. Raster charts generally provide more information and look familiar. Vector charts contain all needed depth soundings and navigational data but less information on shore and other features. Both raster and vector charts come from NOAA and can generally be trusted.

  • Navigating functions and features. These apps vary considerably in features. In all, you see your boat moving on the chart and can mark some sort of waypoints on your chart. Some allow you to create a route you can then follow when navigating. Only one has a rich list of navigating features more advanced sailors will like.

  • Extras. Some apps have special features like the ability to overlap satellite maps or share your track log via social media. While these bells and whistles look good on a list of features, they have little to do with the experience of navigating a boat by an app's chart and probably shouldn't have too much influence over your choice.

  • Speed and ease of use. If you're actually using a charting app (as most do) for information and support when on the water - such as to avoid a rock or stay within a narrow channel - then you want it to work perfectly and fast enough to avoid getting in trouble.

  • Price. I hesitate to even mention price as a factor since after a few weeks of using any app on the water you'll likely care less about whether it was free or cost you $20. Often you get what you pay for, and choosing a navigational product simply because it was free could endanger your boat or even your life if it fails you when you really, really need it.

The apps described here are available for Android devices. For Apple devices, check these apps.

GPS Long Distance Log is a logging app for Android - not a plotter but a good system for logging a voyage.

The free Course to Steer Android app is a nice addition to your navigation toolbox: it calculates precisely how to steer to compensate for a current and leeway from the wind - something most plotting programs do not do.

Looking for a waterproof case for your smartphone or tablet? Check out this one.

Remember that any electronic device can fail at any time, so don’t depend on only a chart app. To be prepared, learn also to navigate with just a depth finder and a chart.
