Most of your health journey happens outside the clinic.
Between clinical visits, most of us are on our own with the everyday choices that shape our health.
QPER Health is designed to provide clearer direction during that time. We focus on cardiometabolic health and the lifestyle factors connected with prediabetes and diabetes, hypertension, and overweight and obesity.
Having a health challenge does not mean someone is not trying hard enough or does not understand what to do. The interconnected nature of the body makes improving health through lifestyle change a long, complex, and often lifelong journey. Progress may also show up in ways that are easy to miss.
Without a map and the right tools, it can be difficult to know where to begin, whether your efforts are working, or what to do next.
The patented QPER Health Map is a personalized health GPS in your pocket. Home-use devices help you track measurable changes from the comfort of home. QPER Health’s intuitive INPUT/OUTPUT approach connects what you do with how your health responds, while QPER Health Age brings those changes together into one connected view of your progress.
QPER Twin adds personalized AI support through a chat-like interface on your phone, helping you understand your progress, ask questions, and navigate what comes next.

I built QPER Health because of my father. Today, I use it for my own family.
My father lived with diabetes, hypertension, and weight-related health challenges for more than four decades. Watching him manage these closely connected conditions made me think about what people need between clinical visits, when they are largely on their own.
I made a promise to build simple, accessible tools that could help people take a more active role in their health from the comfort of home.
I am an engineer by training and have spent my career working at the intersection of engineering and medicine. My research has included chronic kidney disease, red blood cell lifespan, osteoporosis and diabetes drug-response modeling, obesity, and hypertension.
That work taught me to look at the body as an interconnected system. But QPER Health did not begin with a model. It began with my father.
Today, I use QPER Health myself. As a husband and father, I want to do what is reasonably within my control to give myself the best chance of living a healthier, longer life and being present for my family.
My own journey has not been perfect. I made progress, drifted away during the holidays, and then used my Health Map, measurements, and tools at home to see where I was and begin again.
That is what QPER Health means to me. Not perfection, but direction, so that when life happens, you can find your way forward again.
