HEALTH INTELLIGENCE YOU CAN INTERROGATE Your health data should reveal more than a score. BioMIR reveals what drives your modeled biological age, prioritizes practical actions, and lets you compare recorded follow-through with longer-term biomarker trends. Explore the result. Inspect its drivers. Take action. Follow the trajectory. Glance at BioAge on Apple Watch; explore the details on iPhone and iPad. No dedicated wearable required. ONE INDEX. 15 INPUTS. THREE DOMAINS. Adaptive BioAge integrates 15 selected inputs across three roles: • Behavioral — activity, nutrition and daily routines. • Functional — autonomic regulation, sleep and aerobic fitness. • Cardiometabolic — BMI, systolic blood pressure and fasting glucose as a slower-changing baseline. Inspect contributors, biomarker values, sources and dates. Their modeled age-equivalent effects (Δ-years) are relative to chronological age—not years of life gained or lost. FROM INSIGHT TO DAILY ACTION Start in Today with a daily brief you can read or hear. Explore the factors shaping Adaptive BioAge, then follow Top Action to a practical step linked to a priority biomarker. Today Actions consolidates related recommendations. Record completed or skipped actions, set an evening check-in time and enable an optional reminder. RECLAIMED BIOAGE: MAKE FOLLOW-THROUGH VISIBLE Reclaimed BioAge (REC) is a distinct, action-linked biological-age model. It assigns bounded Δ-year credit to recorded completion of eligible actions relative to the eligible opportunities in a selected period. Explore Reclaimed % and Completed Actions % separately. Compare follow-through with later Adaptive BioAge and biomarker trajectories while keeping action credit distinct from physiological changes. TRENDS YOU CAN INTERROGATE Move from daily details to yearly patterns in Dashboard and Trends. Scrub charts to inspect dates or periods and reveal ranked Δ-year contributors. Compare domains, examine fitted direction and see how often contributions remain within defined Persistence bands. Adherence summarizes recorded action completion, not an observed health outcome. KNOW WHAT SUPPORTS EACH RESULT Data Confidence indicates support for daily estimates. Freshness and original observation dates distinguish recent inputs from carried-forward values; missing data remain missing. With eligible clinical panels, Clinical Long View adds independent Klemera–Doubal Method (KDM) and Levine PhenoAge estimates. Compare those laboratory-based reference points with daily trends while respecting their separate inputs and observation dates. EXPERIMENT BEFORE CONNECTING Use synthetic Demo Data and Custom Simulation histories without changing live records. Tutorials and Resources explain the biomarkers, models, statistics and scientific evidence. With permission, BioMIR reads supported Apple Health data from compatible wearables, apps, home devices and clinical sources. Core calculations run on-device. Available results depend on data history, sources and permissions. ACCESS AND SUBSCRIPTIONS BioMIR is a paid app. Premium, including Demo and Apple Health analytics, requires a separate monthly or annual auto-renewing subscription. An introductory trial may be available to eligible subscribers. Prices and terms appear before confirmation; subscriptions renew unless canceled. GENERAL-WELLNESS AND EDUCATIONAL USE BioMIR's estimates, rankings, REC credits and simulations are scientific model outputs for educational exploration. They do not diagnose, treat or prevent disease, establish causation, demonstrate biological-age reversal or lifespan change, or replace professional medical care.

Your body. Your data. Any device. NextRing App turns the signals from your smart ring into clear, honest health intelligence — and it does the thinking on your phone, not in someone else's cloud. WHAT YOU GET • Today — three daily scores at a glance: Recovery, Effort and Sleep, with the story behind each number. • Sleep — an honest, re-staged night view you can actually read and edit. • Vitals — heart rate, HRV, SpO₂, skin temperature and activity, from live readings to long-term trends. • Body — your BioAGE and body signals, measured against your own history. • Trends & patterns — see how you change against your own baseline, not a population average. • Workouts — start a session, record your route, and see what it cost you. • Cycle & women's health — menstrual phases, fertile window and period prediction, with a calendar you can browse months back and ahead. • Coach — ask your own data a question and get an answer built from what your ring actually measured. • Clubs & sharing — accept your club's invitation with one tap, choose exactly which metrics your coach sees, and end sharing at any time. • Home-screen widget — your day, one glance away. • Your language, your text size — English, German, Spanish, Italian, French and Finnish, and the app follows your iPhone's text size setting. BUILT LOCAL-FIRST Your phone is the system of record. Every score is computed on the device from your own history, and the app keeps working with no connection at all. Nothing leaves your phone unless you switch it on. YOUR DATA, YOUR CALL • Export anytime as JSON, CSV or PDF. • Delete anytime — the data on your phone, and your account with it. • No advertising, no ad identifiers, no third-party analytics. • The account is optional. Sign in only if you want cloud sync, club sharing, the coach, order status for your hardware, or account deletion from inside the app — everything else works signed out. • Cloud sync is off by default. Switch it on with your explicit consent and your ring's measurements are also stored on our EU servers — so you can see them in the web portal and share them with a club you choose, kept up to date in the background. Switch it off and sharing ends. • When you ask the coach a question, the app sends a small set of derived values — scores, trends, deltas — to our EU servers and on to our AI provider. Never your raw measurements, and never without you asking. APPLE HEALTH Optional and read-only. Connect it and your iPhone or Apple Watch fills the activity gaps for the hours the ring was not worn, adds workouts you recorded elsewhere, and cross-checks your sleep. The app never writes to Apple Health. WORKS WITH YOUR HARDWARE Built to be hardware-agnostic. Today it pairs with the Nexum Ring and compatible JC Vital rings and bands; more devices are on the roadmap — so you can change hardware without losing your history. NO SUBSCRIPTION The app is yours after a one-time device purchase. No mandatory subscription to read your own body. — NextRing App is a wellness and fitness product and is not a medical device. It does not diagnose, treat or prevent any disease. For medical questions, talk to a qualified professional.
