Wearable relief

Train your body to fight stress with Lief smart patch.

Listen to the heart

Listen to your heart

Lief is a discreet biosensing patch that measures your heart and breath. Lief teaches you to control your body's natural stress response through gentle, safe biofeedback exercises. Reduce triggered responses and keep mindful and in control throughout your day.

The power of self-regulation

The power of self-regulation

Use Lief throughout your day to improve your self-regulation. Self-regulation is the ability to monitor and positively control your behaviors, emotions and thoughts in-the-moment. When you’re upset, you can calm yourself down. When you’re down, you’re able to pick yourself back up. These resiliency skills are trained with Lief.

Reduce anxiety when it's happening

Anxiety creates knee-jerk responses to triggers, increasing heart rate and shallow breathing. When wearing your Lief, learn to calm your mind, pay attention to your body’s state, and voluntarily control your heart, breath, and mindset.

Choose a routine, then go

Set a routine and train the mental and physical skills to improve self-regulation. Short daily sessions take less than 3 minutes and can be done anywhere at anytime.

Control

Learn to control your heart rate with concentration and focus to increase your performance.

Resilient

Develop a calmer nervous system and mental state that’s more resilient to external events.

Nudge

Reinforce your own unique practice or exercises from your coach or therapist with a gentle nudge.

Calm
