Yes! I use my iPhone for placing caches and have been told that my coordinates were"spot on!" I use the screen shot to take and save about save 5 or 6 photos of the coordinates from the iPhone app. Each time I take a reading, I walk away and return to the spot to make sure that it recalculates the coordinates. Then, I use a coordinate if it shows up the same 3 or 4 times or I average them.
