Index of Subjects Hi, Randy- There’s lots of info on the Internet about cell-phone compasses. The compass hardware in smart phones is a kind of magnetometer, detecting the Earth’s magnetic field. They are notorious for unreliable readings. An “app” is required to display the output of the magnetometer on the screen, but the app just displays what the hardware tells it, so the cheapest one will work just as well as the most expensive. Smartphone compasses do not depend upon the cellular system; you don’t need a cell connection to use them. But you’d probably be better off with a cheap old-fashioned compass. —- Peter Payzant > On Apr 20, 2018, at 14:28, Randy Lauff <randy.lauff@gmail.com> wrote: > > Has anyone downloaded one of the digital compass apps for use on their phone? Can you let us know if you found it good or not? Was it free? Can it be used in areas with no cell coverage? > > Thanks, > Randy > _________________________________ > RF Lauff > Way in the boonies of > Antigonish County, NS.
