There are many different ways to track your heart rate. You can do it the old fashioned way. Just place your finger on your wrist, watch the clock, and count. There are also wearable straps and watches on the market that will measure your beats per minute (BPM). But what’s the fun in that? Thankfully, Azumio developed Cardio Buddy, a touch free heart rate application that can actually calculate a person’s heart rate by detecting the color changes in his or her face. It sounds crazy, but it works. The Cardio Body app is an evolution of Azumio’s Instant Heart Rate (IHR) application, which measures the user’s heart rate when he or she places a fingertip on the iPhone camera. “We took the advanced algorithms of IHR and flipped them to the front facing camera to showcase the technology of getting a heart rate measurement from scanning the color changes in the face,” said Jennifer Grenz, VP Marketing and Business Development, Azumio. “Cardio Buddy stands out as revolutionary use of technology and use of sensors in the phone to gather bio-feedback.” Using CardioBuddy CardioBuddy is incredibly easy to use. Opening the application boots up the iPhone’s front facing camera along with a frame in which the user places his or her face. Tapping the frame starts the scan. In about 20 seconds, the application displays the user’s heart rate. From there users can choose to save the result or discard it. Users who are interested to see how their heart rate changes in certain situations or different times during the day can view saved results in the app’s Heart Lab section. “As people can start logging heart rates consistently throughout the day, they can start detecting trends that can be influenced by exercise, coffee, alcohol and stress,” Grenz said. “Knowing what your body is going through by your heart rate will help a person make choices about what to do next in their day.” The heart lab is also quite fun because it allows users see how their heart rate compares to averages in other countries as well as animals. CardioBuddy is not ideal for people who need to monitor their heart rate to treat medical conditions or users who are interested in detecting atrial fibrillation. It’s more of a fun conversation starter. In fact, minutes after downloading it to my phone, I was comparing my BPM with others in the office. My lowest BPM was 48. How about you?
