If you have an iPhone, it might be time to give it a healthy upgrade. iTMP Technology Inc., a hardware and software developer for iPhone, has created new technology that allows the iPhone or iPod touch to act as a heart rate and fitness activity monitor. Dubbed SMHEART LINK™, the device acts as a “wireless bridge that collects data from distributed health and fitness sensors such as heart rate monitors and cycling sensors and sends it to the iPhone via Wi-Fi.” Users can then upload collected information onto various health and fitness tracking websites. “When doing any kind of cardio exercise, most people would agree that the single most important metric to monitor is heart rate,” states Michael Williams, founder and CEO of iTMP. “At iTMP, we are really excited to introduce the first iPhone health and fitness apps that allow the iPhone to listen to your heart.” For more information on this app, visit www.smheartlink.com.
