I have recently acquired a new smart phone, a Samsung Galaxy IIIS. I would like to use it as a GPS for backpacking. It is an Android system phone.

I have done some research here and elsewhere as well. It appears there are four likely contenders: Backcountry Navigator, MotionX, ViewRanger and GPS Test. Reading descriptions and reviews, they all look good, and not being very tech savy, I don't know what some of it means and I don't know what is not being said.


Does anyone here have enough tech savy or experience to know which of these I should be looking at? Many thanks. best, jcp
