How it works

When we started designing Tattle-Tale Heart, we asked ourselves: what exactly can be determined from a person’s heart rate? We spent months studying real-time heart data (collected from people’s webcams) alongside browsing behavior (mouse clicks and DNS logs). The results were stupendous. Subtle variations in heart rate can indicate whether a person is depressed, in love, stubborn, or an impulse spender — to name a few.


From this study, we developed ground-breaking algorithms that crunch heart rate data to calculate mood and personality traits. We wanted to use this technology to get people boldly in touch with themselves and each other. When you wear Tattle-Tale Heart or download the app, you get a window into your most intimate emotional being, and open up your true self for the world to see.
