From playing games to paying bills, smartphones have made almost every aspect of life a little bit easier. That applies to saving money on gas as well, as Forbes magazines recently unveiled its list of top iPhone apps that can help drivers reduce the amount of cash they spend on filling up at the pump.

Perhaps the most useful program is the AAA TripTik Mobile. This easy-to-use app provides drivers with the locations of the lowest-priced gas in the area. Not only that, but it will also give them turn-by-turn directions to make finding the gas station even easier.

In addition to finding the best-priced gas, apps can also help drivers maintain their fuel economy. According the publication, the Gas Manager program can do everything from tracking a car's gas consumption to miles traveled and even its environmental impact.

Along with picking up a few apps for their iPhone, drivers can also save money on gas by getting behind the wheel of a fuel-efficient car such as a Ford Focus or Toyota Camry. Those in the market for a used car can head to New Jersey Auto Auction, which offers plenty of makes and models at affordable prices.
