Yeah, you were aware that your iPhone has multiple functions: as a travel mate, an entertainment media, a learning tool as well as a communication device. And now, a research project found that the iPhone could be a heart monitor and fitness tracking system.

According to Michael C. Williams, founder and CEO of iTMP Technology, Inc., they wanted to make the fitness tracking experience cool, fun, simple and custom. "We did it by leveraging the iPhone's technology."

"There are dozens of fitness apps on the iPhone but none of them, until now, employ heart rate monitors or other sensors." Williams said from his company's headquarters in Santa Barbara, California.He added that the iPhone can now double as a heart rate monitor and bike computer, tracking and storing workouts and even sending the data to medical assessment websites.
