When it comes to matters of the heart, can the brain really provide the right answer? A new take on matchmaking app Tinder, as imagined by a design agency, eliminates thinking and lets you find out who you really like by measuring your heart rate.

In the video above, the Apple Watch concept app uses the device's heart-rate monitoring feature: You simply look at the photo on your Watch, and the app decides whether it's a match by measuring changes in your heart rate.

The principle is simple: If your heart rate goes up, it's a match; if it goes down, it's a no-go. As the agency puts it, "The heart doesn't lie!"

We're not exactly sure about the science behind this idea, but it would remove one step — swiping — from the matchmaking experience, so it could actually be a cool way to use Tinder when that perfect summer storm of laziness and boredom kicks in.

The promo video shows only the Apple Watch, but the agency claims the app is "coming soon" to both Google Play and Apple's App Store. Since the app is not actually from Tinder itself, we suspect the branding may be altered somewhat when it arrives, if it ever appears at all.

We've asked the agency whether they've actually developed the app or whether the video is just a concept. Even if it's fake, the idea is a clever take on how dating apps might evolve in the wearable era.
