About Us

What We Do

Cardihab™ is a digital health company that exists to help patients reach optimal health when at risk of, or living with, heart disease. Our scientifically validated Digital Cardiac Rehabilitation (DCR) solution uses smartphone apps and web portals to give clinicians the ability to deliver more convenient, flexible and engaging cardiac rehabilitation services to patients. Our solution has been demonstrated to increase cardiac rehabilitation uptake, adherence and completion rates, which means better outcomes for patients, clinicians and health service administrators.
