The Pro version is for the data lovers, professionals, and coaches. The Pro can sync your continuous HRV data to a web dashboard where you can analyze, graph, and export your data into other 3rd party programs.
Your Pro also comes with more memory (128 MB vs 64 MB) so it can record without syncing to the app for up to a month.

Exercise your Resiliency.
Lief's 3 minute biofeedback exercises have shown an average HRV increase of 140%.
Choose a routine then go.
Lief uses short 3-minute biofeedback exercises or “doses” as a central training tool in building long-term results. By practicing throughout the day, you can maintain your physical and emotional resiliency while staying focused and balanced.
Measure what matters
No Screens Necessary
Put Lief on in the morning, then forget about it. When your body needs a reset or it’s time to train, Lief's quiet vibrations make sure you're the only one that notices. You don't need a screen to understand what's going on, or what to do next. Just notice the vibration and follow along with your breath.
Insight into the Mind
Developed with Stanford and UCSF clinicians, the Lief support app helps you record your thoughts, emotions, behaviors, and sensations. The app combines with Lief to uncover and untangle thinking patterns that are negatively affecting your body.

The Lief measures your heart rate variability (HRV) to recognize your stress patterns with clinical-grade accuracy. HRV is the healthy variation in your heart rate, and it can act as a robust biomarker of stress and psychological health.
High HRV is generally highly desirable, indicating a calm, focused state. Extremely low HRV, by contrast, is a clue something may be off with your autonomic nervous system.
When your mind and body are relaxed, your heart naturally speeds up on each inhale, and slows down on each exhale. This creates high HRV, and a gentle wave pattern in your heart rate known as respiratory sinus arrhythmia.
The Lief allows you to improve your HRV by breathing with your heart's intrinsic rhythm. This resonant breathing exercise, known as HRV biofeedback, is a simple and safe way to amplify your HRV wave.
The Story of Lief
Lief’s journey began in Harvard and Stanford neuroscience labs studying meditation’s effect on the human brain. After discovering first-hand that meditation techniques truly did have a positive impact on people’s health and wellbeing, we spent nearly a year trekking through the Himalayan mountains to measure the brainwaves and heartbeats of meditating Tibetan monks.
The journey was profound, discovering first-hand the power a trained mind can have over the body, and how deeply the heart is connected to our minds. These masters demonstrated their ability to change the temperature of their body, speed up and slow down their heart at will, and perhaps most profound was their clarity and empathy.
Eventually we returned to San Francisco to use our personal, scientific, and data learnings to turn over a new "Lief" and build the product we have today.
