If you haven’t yet heard of Runkeeper, it’s time to familiarize yourself with this outstanding fitness tool. Using a censor on your cell phone, Runkeeper tracks your time, calories, distance and much more. Runkeeper isn’t just for marathons or sprinters. The service will track walking and biking, along with practically any manual exercise.

By listening to the company, you begin to get a sense how serious they are about providing value for their users. Runkeeper notes how the big guns are trying to duplicate their success, to no avail:

"All of you big guys jumping in with major marketing budgets; you are doing this as a brand play. We are not. You are doing this to try to ultimately sell more people your footwear/apparel. We are not. You are big and slow moving. We are not."

Indeed, Runkeeper is the real deal and continuously improves its service for the sole purpose of benefiting their tightly knit running community. They’ve even launched a Foursquare app.
