We poll NOAA's data servers for the latest chart updates every week and push those updated charts directly to your device. Now, you never have to worry about having the latest charts.
iPhones, iPads ("G" models) and most Android devices have actual GPS support - without cellphone reception. Our apps take full advantage of this embedded GPS capacity...and a host of external GPS devices.
Never worry about not having an Internet connection. Using our innovative offline technology, simply drag and drop your charts and have them everywhere you go. No limit to how often or how many.
