Lifetimer is a private biological-age dashboard for people who track HealthKit signals, blood markers, and longevity habits. It reads Apple Health data when you allow it, computes Levine 2018 PhenoAge on-device, and turns the result into a practical healthspan plan. WHY LIFETIMER Most longevity apps either ask for subjective quizzes or hide useful detail behind a generic score. Lifetimer is built for people who want a calm, native iOS dashboard with transparent inputs, trend context, and next actions. WHAT YOU GET - Apple Health native: HRV, resting heart rate, sleep, steps, weight, VO2 max, and supported health records. - PhenoAge on-device: biological-age estimates from nine published blood markers. - Biomarker log: track blood panels, manual entries, and scan-derived lab values. - Intervention plan: ranked lifestyle actions with expected delta, evidence grade, and citations. - Cohort view: local percentile context without uploading your private health data. - Widget: glance at your biological-age delta from the Lock Screen or Home Screen. LIFETIMER PRO Lifetimer includes a paid Pro subscription for deeper longitudinal tracking and export workflows. - Monthly Pro: $9.99/month - Annual Pro: $59.99/year Subscriptions are charged to your Apple Account and renew automatically unless cancelled at least 24 hours before the end of the current period.
