An adult-only wellness model

The everyday Biological Age method combines available eligible wearable and lifestyle inputs. It requires adult eligibility, eligible paid access and sufficient data. It is a Connefi-specific model, not a medical test or a validated DNA-age test.

Inputs change the picture

Eligible inputs include cardiorespiratory fitness, resting heart rate, HRV, sleep, waist-to-height ratio, activity and strength frequency. Missing inputs affect coverage. Different sources and HRV methods are not interchangeable.

Keep the limits visible

An estimate does not establish rejuvenation, longer lifespan or a medical condition. History and projections depend on the available inputs and recording period. Laboratory-derived PhenoAge is a separate method with different inputs and meaning.
