Meet the first AI wearable that transforms how you feel.
You have the ability to transform how you feel. It’s a skill, and we’re here to help you build it. With Lief, you’ll learn how to train your body to stay calm and focused when you need it most.
Lief measures your heart and breath to track your stress levels in real-time, using a clinically-proven biomarker of stress called heart rate variability (HRV).
When you're under pressure, learn to control your body's natural stress response through gentle, safe biofeedback exercises. Practice when you need it by following the vibrations. It's just 3 minutes, and you can do it anywhere.
As your average HRV increases, you'll feel the difference and experience the power of calming your mind on-demand.
Lief improves your heart rate variability, a scientifically-proven biomarker of mental health. Follow the vibrations to build awareness of your triggers, then self-regulate in the moments you need it most.
Lief AI is supported by Stanford-trained clinical psychologists, therapists and health coaches who care deeply about your mental health.
Take your training goals to the next level with live chat and video sessions. Use as little or as much as you need.
We’re a drug-free solution to stress and worry backed by empirical research, as well as decades of evidence on heart rate variability biofeedback.
