Lief improves your heart rate variability, a scientifically-proven biomarker of stress. Follow the vibrations to build awareness of your triggers, then self-regulate in the moments you need it most.

How The Lief

Program Works

Track with Lief

The Lief is the most intelligent, clinically accurate HRV wearable device for mental health, and the only one that can intervene in real time to help your body de-stress.

Train with Coaches

Your Lief coach will chat with you one-on-one to share mindfulness building tips and answer any questions.

Transform how you feel

As your average HRV increases, you'll feel the difference and experience the power of calming your mind on-demand.

Reviews

Huge potential to help its users better understand the emotions they're feeling, and their impact on health.

Chrissy Farr, CNBC

Teaches your body to calm itself down.

Grant, San Francisco

As a person who has been struggling with anxiety for much of my life, Lief is a refreshing approach to dealing with moments of anxiety. The vibrations actually conditioned me to be more aware of my breath when I'm anxious.

Rachel, North Carolina

Having immediate feedback when my HRV dramatically changes as a result of stress is a huge insight.

Ann, New York

If you are one of those people who gets anxious, stressed, or nervous a lot during the average day then this smart patch wearable could be for you.

Getting to know your triggers can help you prepare for them. HRV is a real thing!

This stress-reducing device may be the answer to daily anxiety. A small price to pay to master the art of zen.

Helps you manage your body's natural stress response.

Received my Lief yesterday. I put it on the next morning, and did the first exercise… It worked so well for my morning panic attack.

Macy

I've found my Lief enormously useful! My Lief has made a significant improvement to my overall stress/anger levels.

Michael

After having the heart-rate feedback on for a few weeks, I 'learned' to catch myself when I started to get tense. I can also now slow my heart rate at will, which I would never have thought possible. It's amazing.

Tomas

This device has been so helpful for my PTSD and my self regulation.

Stella

I finally learned how to regulate my own anxiety by understanding the relationships between my breathing, my heart rate, and my heart rate variability.

Sterling

Great way to detect stress the moment it hits and get vibration based HRV-synchronized breath coaching immediately from this wearable, without looking at your phone or relying on the phone's vibrations!

Dan

Best tool to track hrv and give real instant biofeedback.

Andrew

It's a wonderful tool to help you learn meditation and how to calm yourself. It helps relieve stress and you feel more in control. The stress reduction program is an excellent teaching tool also.
