The application uses the same satellite and aerial photography found in the desktop version, only this time you navigate the globe simply by swishing your fingers across the screen. It’s advisable to have a look at the controls system in the program’s Help section before you start using Google Earth on your iPhone, because some of the commands aren’t immediately obvious.
