Meet Pathr

Pathr is a marine navigation app that brings nautical charts, boat position, and voyage planning to a phone. Its charts use official NOAA data, including soundings, contours, and navigation marks, and can be downloaded for use without a connection. An anchor watch lets a boater set a radius and receive an alert if the vessel moves outside it.

Premium tools add routes planned around a boat's draft, AIS vessel information, and marine weather layers. Routes are prepared while connected and can then be followed offline. The app is intended to help boaters assess their surroundings and plan a passage, with the relevant depth, traffic, and conditions visible together.
