Useless for what I wanted.

What I hoped to find was an inexpensive app for my Mac that would let me define waypoints on nautical chart so that I could then transfer them to my iNavx on my iPad. Unless I missed something, this app will only support waypoints within the context of a route. The concept of a stand-alone waypoint doesn’t exist. When I imported a bunch of stand alone waypoints that I had previously defined in iNavx, the app created a route to connect them all. Not at all what I had hoped for.
