As gas prices soar, here are tips to help find cheap gas with your smartphone

Gas prices have been soaring lately across America and will continue going up if demand increases, the American Automobile Association says.

National averages reached $3.41 a gallon as of Thursday, with California stations charging as much as $4.68 per gallon, according to data from AAA.

Given a typical 15-gallon gas tank, that means Americans are spending on average about $19.50 more each time they go to the pump, compared to the same time a year ago.
