Store description excerpt
Longevity Counter turns established mortality and epidemiological evidence into a clear, personal estimate of how long — and how healthily — you're likely to live, with a live counter of your estimated remaining time front and centre. It is honest by design: it never claims to predict your exact lifespan and never shows a date of death. Every figure is a population-level probability that updates as your data improves. WHAT YOU GET • Live counter of your estimated remaining time (Home screen + Home/Lock-Screen widget) • Estimated lifespan, a likely range, and your "longevity age" vs your real age • Healthspan estimate — how long you're likely to stay largely disability-free • Probability of reaching 70, 75, 80, 85, 90, 95 and 100 • Six scores: overall, cardiovascular, metabolic, fitness, lifestyle, recovery • Your top factors helping and hurting you, and the highest-leverage things to change • Scenario modelling: what happens if you optimise your modifiable risks — or if they slide BUILT ON EVIDENCE, NOT HYPE The model starts from an age- and sex-specific mortality baseline and adjusts it with published, all-cause hazard ratios from large cohort studies and meta-analyses (blood pressure, smoking, diabetes/HbA1c, ApoB/cholesterol, fitness/VO₂max, adiposity, activity, alcohol, kidney disease and more). Correlated inputs are grouped so they aren't double-counted, and consumer-wearable signals like HRV are deliberately kept from dominating. Every component shows its source, study, population, effect size and evidence strength. PRIVATE BY DESIGN • Local-only: your data stays on your device • No account, no tracking, no analytics, no ads • Export/import your data as a file whenever you want APPLE HEALTH & WEARABLES • Apple Health (HealthKit), read-only: VO₂max, resting heart rate, HRV, steps, sleep, body measurements and blood pressure are imported to fill in your profile automatically. Connect it from the Health tab. The app never writes to Apple Health, and your Health data never leaves your device — it is never uploaded, never used for advertising and never shared. You can review or revoke access any time in the Health app. • Oura: connect with Oura's own secure sign-in (OAuth) — the app never sees your password • Garmin: coming soon The app prefers 30/90/365-day averages for stability. IMPORTANT Longevity Counter is a statistical estimate based on population-level evidence. It cannot predict your exact lifespan, never predicts a date of death, and is not a medical diagnosis or a substitute for professional care. Always consult a qualified clinician about health decisions. From VyteraLabs — vyteralabs.com
