Gas Buddy

Nobody likes overpaying for gas, but sometimes you just need to get to a pump pronto. Gas Buddy can help. This app for iPhone, Android and Blackberry devices displays gas stations in your vicinity along with the gas prices offered by each station. The Gas Buddy app serves as the mobile version of the full-featured Gas Buddy website. A community of contributing users provides the information, which may mean you’ll get more accurate price data in bustling urban areas than you will in less-traveled rural locations.

FuelLog

FuelLog does more than simply monitor fuel consumption. This Android app does that, certainly, but it also gives you tons of information on your particular model’s fuel economy, maintenance and other operational costs, fuel volumes used and more. It presents this information in a clear, logical graphic interface. It even works for electric cars by displaying electricity usage per hour, and it can also track costs for multiple vehicles.

Car Locator

The free Car Locator app for Android devices can help you figure out whether you’ve simply forgot where you parked, or you’ve fallen prey to auto theft (which occurs every 44 seconds in this country, according to the Rocky Mountain Insurance Information Association). It gives you the option of a radar-like proximity visualization or a wallpaper displaying the distance to your vehicle, complete with a helpful arrow to point the way. Bear in mind, though, that you have to save your location to the app before leaving your car. You can also send the location data to someone else’s phone or email.

Trapster

If you frequently drive along unfamiliar stretches of road, you can easily get slapped with a speeding ticket in the most unlikely places. Trapster, a free app available for iPhone, Android and Blackberry devices, levels the playing field by alerting you when you are near a known enforcement camera, road hazard or speed trap. CNN describes it as a “cell phone social network” powered by crowdsourced reports from thousands of users who want to warn their fellow motorists when they need to slow down.
