Lief - Smart Patch that Fights Stress

Lief is a wearable patch that helps you build long term resiliency against stress. Worn just under your heart, Lief tracks your heart rate variability, a measure of how calm and focused you are. It then leads you through a series of scientifically backed exercises to help you manage stress in the moment and over the long run.

If you haven’t heard of heart rate variability before don’t worry. This term has only recently entered the public conversation. But scientists have been studying it for years, and believe it could be THE most important measure of calm or stress.

Lief is one of the first products to help people improve their heart rate variability, and thus achieve new levels of zen-like calm
