Don't Worry, Be App-y
Along with playing Angry Birds and taking pictures of your cat, smartphones are incredibly useful for car owners, offering free apps that can help save both time and money.
Here’s a list of apps that we find the most useful when it comes to driving and car ownership. Many apps on this list are at least available for both Android and iOS handhelds, while some also support BlackBerry and Windows Phone devices.
Finally, we should point out that while many apps are easy to use, it isn’t safe to use your smartphone while driving. Instead, pull over and check your phone or give the device to a passenger while you keep your eyes on the road and hands on the wheel.
