Carticipate- This app can help you find people heading in the same direction as you to help coordinate carpooling. Save the environment at the same time as you save money, and perhaps make a friend or two along the way!
iGasup- Ever wondered where exactly is the cheapest gas in your area? Wonder no longer; this app can help you compare the gas prices at all the stations near you to help you get the most for your buck.
Trapster- You'd never knowingly speed, would you? Of course not! But on the off-change that you're known to get a bit heavy-footed from time to time, download Trapster to help inform you of police speed traps before you reach them.
TripAlyzer- Trying to maximize fuel efficiency during your drive? Download this app to help keep track of stats and driving habits during your trip to help you save the most money at the pump.
Craftsman Garage Door App- This is arguably the coolest app on this list. Ever gotten to work or well on your way somewhere and wondered: Did I remember to close the garage? This app for the iPhone can help set your mind at ease (or let you know if you need to hightail it back) by letting you know if your garage door is open or closed. The app itself is free, however the technology needed to keep track of your garage door can cost about $200 at Sears. We're thinking that might be worth the peace of mind, though.
