QuantiQi gives you a real-time, quantifiable measure of your vital energy — so you can know your current state, track your growth, and take meaningful steps toward a longer, healthier life.
Classical Chinese philosophy defines Qi (AKA Chi) as the origin and dynamic substrate of life. Each person has a complex network of communication channels — hormonal, neuronal, circulatory — that work together to manifest health, well-being, and mental alertness.
When these internal systems work in harmony, a person exhibits Qi that is balanced and strong. Higher levels of Qi can be cultivated through intentional lifestyle choices — movement, rest, nutrition, and mindfulness — enabling the body to function at its fullest potential while sustaining that inner balance.
Aging, unhealthy lifestyles, and disease erode these channels and their feedback loops, resulting in decreased coherence and diminished function. These effects accelerate without proper self-awareness.
Healthy levels of Qi exist at every age. Like body weight or blood pressure, Qi can be represented as a number — providing a meaningful baseline and a clear direction for growth. We look for the complexity and quantity of energy that you express throughout the day.
Similar to how the energy of a star is revealed through the light and energy it expresses, QuantiQi measures the physiologic signals your body expresses as a window into the state of your Qi.
Although people are living longer, the added years are not always healthy ones. We encourage people to track and grow their Qi as a way of aging with grace and vitality, and prolonging their healthspan — the years spent in genuine vitality.
Qi is a direct indicator of health and longevity. Higher Qi is associated with better functioning physiologic systems. Monitoring your Qi can detect deviations before they become problems — giving you the information to act.
Higher Qi is associated with better functioning systems across every domain — cardiovascular, neurological, metabolic. It is a holistic indicator of how well your body is operating.
Monitoring Qi over time reveals when your system is trending away from its healthy baseline — often before you feel symptoms. Knowledge enables action.
Knowing your Qi enables you to make intentional choices. Movement, time outdoors, community, and mindful inputs all influence your score — and you can see the results.
QuantiQi gives you a repeatable, meaningful number that reflects your current vitality — and shows you how it changes over weeks, months, and years. Like a scale for your energy.
QuantiQi captures the energy of your students and patients. Whether you're teaching martial arts, practicing acupuncture, or supporting someone's long-term health, Qi data deepens every conversation.
Compatible with many wearable devices including the Apple Watch, Oura Ring, Garmin, Fitbit, and others — any device must be able to measure heart rate. No changes to your routine. The app installs via TestFlight (beta) or the App Store at commercial launch.
QuantiQi passively monitors your heart rate dynamics, activity, movement patterns, and environmental signals — all day, effortlessly. No starting or stopping timers.
Our algorithm analyzes signal complexity — the core biomarker linked to Qi in peer-reviewed research — across multiple channels to compute your personalized Qi score in real time.
View your Qi score and breakout analyses on iPhone. A companion app helps you visualize your data directly on your wrist — so you know how your day is shaping up throughout the day, not just at the end of it.
"We apply the tools of Western science to understand Eastern medicine."
Our proprietary assessment method is grounded in peer-reviewed research linking physiologic complexity with Qi, aging, and health outcomes. The science is robust and repeatable. The experience is simple.
The closest proxy to Qi in a Western Science context is blood flow — because where the energy goes, blood flows.
Ancient Chinese philosophy and traditional medicine teach that life itself is a manifestation of Qi — the vital energy animating body, mind, and spirit. When Qi flows freely and in balance, we flourish. To better sense its strength is to know more clearly the state of our vitality.
Dr. Greg Hall devoted 25+ years developing FDA-regulated medical devices — building expertise in physiologic algorithms, sensor systems, and the translation of complex signals into clinical insight.
At the 2024 Integrative Medicine Network Forum, Dr. Hall observed something that stayed with him: audience after audience, deeply curious about Qi — what it is, and whether it could ever be measured. He saw an opportunity to apply his expertise to answer that question.
QuantiQi was born from that moment — a platform for personal growth, community-building, and the quantification of human vitality.

Engineer and medtech executive with 25+ years developing FDA-regulated medical devices. Named inventor on 35+ issued US patents. Founder of Chaparral MedTech LLC. Inspired by the intersection of Western science and Eastern medicine at Harvard Medical School's 2024 Integrative Medicine Forum.
Our engineering team translates complex physiologic algorithms into a seamless, intuitive experience — making the science of Qi accessible to everyone.
QuantiQi is guided by advisors spanning wellness medicine, wearable platform development, and medtech commercialization — ensuring the product is clinically meaningful, technically excellent, and built to scale.
QuantiQi is currently in development. We're recruiting beta test participants to help shape the app before its commercial launch.
Beta participants will receive 6 months of complimentary access to QuantiQi upon commercial launch, along with the opportunity to give feedback that directly shapes the product. Requires a compatible wearable device and iPhone.
Our goal is to make an app that is useful and usable. Whether you're interested in the beta study, have questions about the science, want to explore professional applications, or simply have a suggestion — reach out. Your feedback shapes what we build.
