Personal Longevity Intelligence
Most people over 40 are
aging faster
than they think.
Your chronological age is just a number. Eumaia tracks how your biology actually responds to interventions — so your plan gets sharper every time you retest.
Based on the PhenoAge research framework (Levine et al., Yale, 2018)

What the research shows
The silent gap between your age
and your body's age
A 2021 pilot study (Fitzgerald et al., Aging — 8 weeks, n=43, single-arm) found that adults following unoptimized lifestyles carried a biological age 3–7 years older than their calendar age — without knowing it. That gap compounds silently every year.

Intelligence infrastructure
Not a tracker. A digital twin.
Platforms like Apple Health and InsideTracker give you diagnostics — they measure. Eumaia gives you intelligence infrastructure — it models, simulates, and longitudinally tracks how your biology responds to intervention over time.
Digital Twin Simulator
Ask "what if I fix my sleep, lower my glucose, or add Zone 2?" and model how each change may influence your biological age estimate. A modelled scenario — showing how your PhenoAge estimate would change if specific biomarker values shifted as modelled. Not a prediction of personal outcome.
Try the simulator →Biological Age Score
Your estimated biological age — calculated from 9 validated blood biomarkers using the PhenoAge algorithm developed at Yale.
AI Expert Panel
Research-informed recommendations drawn from the publicly available work of Levine, Patrick, San Millán, Bikman, and Huberman.
6 System Age Tracking
Heart, brain, metabolic, inflammation, muscle, and lung ages tracked separately — so you know exactly where to focus.
Peer Benchmarking
See how your biological age compares to anonymized peers in your age cohort — ahead or behind.
Longevity Killers Audit
Discover hidden daily exposures silently accelerating your biological age — from food to air to cookware.
ExploreThe honest question
Why not just use Apple Health,
InsideTracker, or Function Health?
Those platforms
Provide diagnostics — they measure what you are today
Show results but don't model what changes them
Are optimised for hardware, lab kits, or wearables
Can't simulate "what happens if I fix my CRP in 90 days?"
Eumaia
Provides intelligence — it models and simulates your aging trajectory
Runs your biomarkers through a digital twin and shows what moves them
Tracks intervention response longitudinally — did the protocol actually work?
Gets smarter as you add data — labs, wearables, genetics, habits
The short answer: they provide diagnostics. We provide intelligence infrastructure. Use them together.
