Lief

Lief helps you feel your best by managing stress in real time by tracking your breathing and heart activity.

Stress is a part of modern life, but its long-term effect on our health and productivity can be dramatic. Chronic stress can literally kill you, increasing your risk for heart attack and stroke by up to 50%.

Lief tracks and optimizes your resiliency to stress by increasing your natural heart rate variability (HRV), a biomarker of your physical and psychological health. A low HRV score is linked with anxiety, distraction and poor performance - things we'd all prefer to avoid.

The good news is, you can improve your HRV and train yourself to stay focused and in control throughout your day. The device's scientifically-validated HRV biofeedback exercises have been used by doctors, psychologists and coaches for decades. It's safe, drug-free and has improved stress, mood and focus for thousands of people.
