 We pulled people off the street and asked them about their heart. How's your heart? Good. You sure? I think so. How do you know? It doesn't come with a manual, and you're like, oh, I got the 20,000-day checkup, right? With CardioMobile, you can take a medical-grade EKG in just 30 seconds from anywhere. CardioMobile is a small device about the size of a stick of gum. Simply put your fingers on the electrodes, and your EKG is recorded right onto your phone. CardioMobile has proven to detect atrial fibrillation, one of the leading causes of stroke. How much do you think this costs?
