Wearable tech promises to do many things — track your health and workouts, and even change color to match your outfits — but this wearable tech item claims to help set your mood.

Doppel is a device you wear on your wrist to “make you feel more alert or relaxed,” according to its Kickstarter site. How does it do it? It simulates the way upbeat or downbeat music affects your emotions, but without the distraction, according to its creators, London-based Team Turquoise.

“Doppel has a heartbeat, a double beat pulse that you feel on the inside of your wrist,” the Kickstarter page states. “You can control the rhythm and the intensity of the beat. When Doppel beats at your resting heart rate your mood will shift to being more calm. Upping the beat gets you going.”

The actual device is fairly simple, with no screens or buttons. Simply set it up through an app to calibrate it to your heartbeat. You then change Doppel’s rate by squeezing it or stroking its face, and turning the dial like a volume control.

The team says they’ve tested Doppel on hundreds of users as natural way to help them “stay focused in professional settings, keep up the pace while running and training, and to wind down for sleep. It’s also been independently shown to increase focus and alertness.”

They’ve raised about $95,000 of their goal of just over $155,000 to bring Doppel to market with 10 days to go. A pledge of $109 will get your the stainless steel version of Doppel, estimated to ship by April 2016.
