Begin with today’s full picture configured to your preference.
See Adaptive BioAge, domain trends, and today’s prioritized action together. Swipe through the recommendations or tap
to open the ranked list. Before check-in, tap 
to plan or to consider an action; use 
to undo a selection or 
to reset. At check-in, record 
for a completed action or 
for a skipped one. Eligible completions earn modeled REC age-equivalent credit. Open a card to inspect its contributing biomarkers.
Set the time for your daily action review.
The check-in settings show the selected review time, optional reminder, and persistence-alert preferences. Before check-in, cycle between
and 
; afterward, record 
or 
. Use the panel to set when the review takes place and whether a reminder should prompt it, while separate alert controls let you choose which recurring patterns to follow over time.
Close the daily loop with a recorded outcome.
The check-in summary closes the daily review with 5 and 3 outcomes; the REC counter updates alongside recorded follow-through. Use the totals to see which commitments were completed, set aside, or remain unresolved, then compare the day’s action record with its eligible opportunities and running credit in the same view.
Adaptive BioAge summary
The summary brings the selected estimate together with acceleration, its displayed interval, data support, and ranked contributors. Persistence counts qualifying observations across four contribution bands, while Trend summarizes dated direction; these complementary panels help readers inspect the estimate, its support, and its behavior over time.
Reclaimed BioAge detail
The REC detail separates reclaimable and reclaimed modeled years from action counts and completion percentage. The Adherence table groups qualifying days by earned-credit band, while Trend fits the signed daily record; compare these summaries to understand how opportunity-weighted credit and action-by-action follow-through are represented over time.
Reading the three companion measures
The selected Month · Mean view compares the composite series with its fitted direction (↘), high-band persistence, and reclaimed-credit summary. Read the shaded interval alongside the estimate, then compare threshold frequency and opportunity-weighted credit as distinct longitudinal views; together, these measures help organize direction, persistence, and recorded follow-through across the displayed period.
Following a modeled transition
This monthly view follows a synthetic transition through the composite trajectory, persistence summary, and recorded action credit. Compare the direction of the series with the frequency of higher-band observations and the separate credit record; the combined view helps organize temporal patterns without reducing them to a single indicator.
Focus the daily view on the composite and its contributors.
This minimal arrangement gives the composite more room while retaining contribution rings and recent direction below. Use it when a quick overview is the priority, then expand the remaining cards to bring back action guidance, dated clinical context, or information about the data supporting the current result.Swipe to explore · Tap to enlarge
Inspiration
Inspired by the spirit of a tricorder and the familiar logic of a market index, BioMIR makes your trajectory visible—and the contributors behind its movement open to investigation. BioMIR brings that idea to selected, high-value health signals through an engaging glass-like interface—inviting you to navigate the whole and investigate what shapes your vitality and longevity.
Preventive health, made engaging

A biological time machine—an interactive window into your health history. Scrub to revisit a moment; swipe to follow a trajectory. Explore the signals, habits and patterns in your record—and investigate what changed, what preceded it and what happened next.
Explore the approach
Read the direction in color, hear your daily brief, or move through your history with as much analytic and scientific depth as you prefer—then focus on what deserves attention.
Put persistence in perspective. Follow individual contributors across days, months, and a year to see how often elevated model contributions recur. Bring sustained patterns into your decisions—and keep the supporting data and their dates within reach.

Understanding Δ-years
Read the direction. Negative Δ-years indicate favorable model contributions; positive values indicate adverse ones. Blue and red contribution colors reinforce that direction, while chart hues distinguish domains. These are model estimates, not years of lifespan gained or lost.

Adaptive BioAge
Integrated longitudinal model
Hierarchical composite with an age-calibrated cardiometabolic baseline and bounded, asymmetric Functional and Behavioral Δ-year contributions. The output is expressed in age-equivalent Δ-years relative to chronological age, with negative values representing age-equivalent reward and positive values age-equivalent penalty, while retaining contributor attribution over time.
Klemera–Doubal Method (KDM)
Multivariate biological-age estimator combining age-calibrated biomarker regressions with chronological age.
Levine PhenoAge
Mortality-trained multivariable biomarker score mapped through a Gompertz function to an age-equivalent phenotype.
Cadence depicts characteristic observation and interpretation timescale—not a causal sequence, fixed biological deadline, or prescribed testing interval. Cardiometabolic state is interpreted longitudinally; KDM and Levine PhenoAge use separate clinical-panel context.
Evidence to action · a separate record
Reclaimed BioAge (REC)
REC turns prioritized signals into a short action list and records whether eligible actions are reported complete. Its Adherence view summarizes those reports and can be reviewed beside Adaptive BioAge and later observations, while each remains a separate record.

- 02Choose a useful action
- 03Record follow-through
Conceptual sequence, not measured data; timing alone does not establish cause or response.
What sits beneath the model
Fifteen inputs.
Three complementary domains.
The architecture is intentionally compact: selected signals are grouped by how the model interprets them—not as 15 equal votes.
017 exposure inputs
Behavioral
Modifiable routines and exposures enter Adaptive BioAge as bounded contributors rather than direct measurements of physiological state.
025 physiology inputs
Functional
Autonomic regulation, restorative physiology, and cardiorespiratory capacity provide responsive physiological context across different measurement and adaptation timescales.
033 baseline inputs
Cardiometabolic
A slower-moving age-equivalent baseline anchors the daily composite, with original observation dates preserved when eligible prior values are carried forward.
Adaptive BioAge uses all three domains. KDM and Levine PhenoAge remain separate in Clinical Long View. Reclaimed BioAge (REC) connects prioritized signals with practical actions and recorded follow-through. See how the models fit together ↗
A controlled scientific core
Deterministic science.
Adaptive personalization.
Current core. Adaptive BioAge is computed from prespecified, version-controlled model rules rather than a self-training model. For the same eligible inputs evaluated under the same model version, the scientific calculation remains reproducible and the result can be traced back through domains and contributors.
Future personalization. BioMIR’s roadmap keeps adaptive intelligence downstream of that authoritative calculation. On-device learning may eventually characterize individual baseline, variability, temporal response, and action-response patterns without silently rewriting the equations that produced the underlying BioMIR result.
See the architecture and roadmapA model output expressed in age-equivalent units. A way to put signals into context.
Adaptive BioAge is a model output expressed in age-equivalent units relative to chronological age. Δ-years provides a common signed scale: negative values represent an age-equivalent reward and positive values an age-equivalent penalty. It is not a direct measurement of years gained or lost.
Short-term movement can reflect recent behavior, functional physiology, available data, or model assumptions. It does not establish a change in lifespan.
Interpret the result alongside its contributors, Data Confidence, Data Freshness, and trends—not as a verdict on your health.

Biological age vs. health age: what do these scores actually mean?
Age-like health scores can be useful summaries, but the number only makes sense in the context of the inputs, reference population, outcome, and model assumptions behind it.

Why can a biological-age estimate change from day to day?
High-frequency age estimates are dynamic summaries. Short-term movement can be informative without being interpreted as irreversible aging or lifespan change.
