Resurrecting an oldish thread. . . . I hope we can keep ongoing list of useful Android apps for sailors here.
I just came across this one, after reading a thread on hand bearing compasses, and thinking, "Hey, maybe I could hire someone to write an app that turns my Droid phone into a bearing compass
, and I'll get rich!" A quick check of the Marketplace reveals, of course, that it already exists. And it's free: Smart Compass
It looks "through" the phone using the rear-facing camera
, and shows the compass
bearing superimposed on the view. Very simple and elegant.
I find this app is accurate to a degree or two, using some known landmarks near me. Just keep your phone's electronic compass calibrated, by giving it a few rotations in all directions.
