Most biological age calculators stop at cardiorespiratory fitness, HRV, and sleep. My Bio Age takes precision further with optional Blood Pressure support that enhances your MyBioAge Index calculation. For users who track BP with an external monitor, this upgrade unlocks two additional metrics—systolic and diastolic pressure trends—transforming the core 12-metric model into a 14-metric advanced system. Critically, BP support is purely additive: if you do not track it, there is no penalty, and your biological age remains accurate based on the standard metrics.

Why Blood Pressure matters for biological age

Blood Pressure is a direct window into vascular health and arterial stiffness, both of which correlate strongly with cardiovascular aging. Elevated systolic pressure increases heart workload, while high diastolic pressure signals reduced arterial compliance. Longitudinal studies from the American Heart Association show that BP trends predict cardiovascular events and all-cause mortality independent of VO₂max and HRV. By integrating BP into the MyBioAge Index, we capture a dimension of aging that exercise and recovery metrics alone cannot fully address.

How the additive weighting works

When you enable Blood Pressure tracking, My Bio Age incorporates BP trends (systolic and diastolic) into your Index while proportionally adjusting the remaining metrics. VO₂max remains the largest contributor, followed by Sleep, HRV, and Recovery Capacity. The recalibration preserves the relative importance of each signal while enhancing overall precision. If you stop tracking BP or never start, the original 12-metric weighting applies, and your score reflects the same scientific rigor without the additional data.

Recommended Blood Pressure monitors for Apple Health

To track BP in My Bio Age, you need an external monitor that writes to Apple Health. We recommend FDA-cleared devices like the Omron Evolv, Withings BPM Connect, or QardioArm, all of which sync automatically via Bluetooth. Take readings at consistent times—ideally morning and evening—while seated and relaxed. The app uses rolling 14-day averages to smooth day-to-day variability and flag sustained trends rather than isolated spikes.

What the app does with your Blood Pressure data

Once BP data flows into Apple Health, My Bio Age evaluates both absolute levels and directional trends. If your systolic pressure is climbing despite stable VO₂max and HRV, the app highlights vascular health as a priority and suggests interventions like reducing sodium intake, increasing aerobic volume, or consulting a physician. If BP trends downward while other metrics improve, your biological age benefits from the combined signal, accelerating your progress toward a lower functional age.

Privacy and control with BP tracking

Blood Pressure data remains on-device alongside all other Apple Health metrics. My Bio Age never uploads BP readings to servers, and you retain full control over permissions inside the Health app. If you want to pause BP tracking temporarily, simply disable the HealthKit permission and the app reverts to the 12-metric model without losing historical data. When you re-enable BP, the advanced 14-metric calculation resumes immediately.

Who should enable Blood Pressure tracking

BP support is ideal for users over 35, those with family histories of cardiovascular disease, or anyone who wants the most comprehensive biological age assessment available. It is also valuable for endurance athletes managing training load, as intense volume can temporarily elevate resting BP. If you already monitor BP for clinical reasons, integrating it into My Bio Age adds zero friction while unlocking significant precision gains.

Blood Pressure support is live now in My Bio Age. Connect a compatible monitor, enable the HealthKit permission, and watch your biological age calculation upgrade to 14 advanced metrics.
