Sorry about the headline. Couldn’t resist. But here are five commuter friendly iPhone apps to try (especially if you’re buzzing around town on your new BRAMMO Enertia). Bike Your Drive is a free app that allows bike commuters to calculate things like how far they’ve biked, how many calories they’ve burned and how much gas money they’ve saved. Transit Maps allows you to store any transit map on your phone. Aha provides real-time traffic info and location searches and even lets you share real-time info with other drivers on the network. Zipcar is a free app that makes being a member of this unique car rental company a snap. You can choose a car to rent, reserve it and even turn it on using your iPhone. Finally, Maps + Compass is a standard app that will help you select the best routes no matter what your mode of travel is. Its bus feature even tells you when the bus will arrive. Check them out. And happy travels!
