Finding a match will be a lot easier now. A new app called "Once" will measure heart rate of those looking for a match, reports Business Insider. "Once" connects to either a Fitbit or Android Wear device, tracking your heart rate while you look at someone's profile.

Once the user feels sympathy for someone, his heart starts beating faster, which gets registered by the app. If after being asked to meet up a prospective date’s heart also starts beating faster, the app gives a sound alert, which means that the two should surely exchange contact info and continue to talk.
