What is a digital health twin?

A digital health twin is a continuously updated virtual model of an individual's physiology, behavior, and care history. It synthesizes data from wearables, electronic health records, lab results, genetics, and self-reported inputs to simulate how that specific person is likely to respond to interventions — enabling personalized, proactive care.

How is a digital twin different from a regular health app?

A health app typically tracks isolated metrics (steps, sleep, weight) and shows you graphs. A digital twin models the relationships between those metrics and your medical context, predicts trajectories, and personalizes recommendations to your individual baseline rather than population averages.

Is my data private and secure inside a digital twin?

VHT.ai's digital twin is HIPAA-aligned, encrypted in transit and at rest, and governed by explicit consent for every data source. You decide which providers, family members, or research programs see which slices of your twin — and you can revoke access at any time.

Who benefits most from a digital health twin today?

People managing chronic conditions, post-operative recovery, complex medication regimens, mental-health journeys, or aging-in-place see the largest immediate benefit. Healthy users gain personalized prevention and early-warning detection that traditional annual checkups cannot match.

Does a digital twin replace my doctor?

No. A digital twin augments your care team by giving them a continuous, contextual view of your health between visits. Clinical decisions remain with your licensed providers; the twin makes those decisions better-informed and timelier.
