The innovative new dating app, Once, monitors your heart's response to a potential lover.
With 100,000 active users already, it's trying to break free from the same old structure of other dating apps.
The app's matchmakers are humans, and give users a specifically targeted match every day at 12pm.
You then get 24 hours to make a move by messaging them. This means you don't have to spend hours on end scrolling through profiles.
It's the first of its kind since adding the additional heartbeat feature.
Working for Fitbit and Android Wear users, you can now see your true reaction to a suitor. The app will record your heartbeat to see whether it is raised when you are shown your match's photo.
It'll then use this data to help you decide whether to message or not.
They're also claiming: "Love at first sight might soon become a reality in the palm of your hand."
Once is for users of any age or sexual preferences, and costs £7.99 a month.
