Apps can help you save at the pump

Here's another thing your smartphone can help you with--saving money at the pump.

Mobile-app hub Appitalism.com put together a list of apps that will help customers find lower gasoline prices.

Cheap Gas, which is free for the Android operating system, helps find the least expensive gas stations near you using your mobile phone's GPS. Gas Mileage Calculator does just that--determines your car's gas mileage and cost per mile. It is also free for Android users.

Free for the iPhone, Gas Price Predictor estimates the next day's gasoline prices based on Web data, and Gas Cubby MPG Car Maintenance tracks gas mileage and vehicle maintenance.
