Lifetimer: Biological Age

Your PhenoAge from real bloods

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

A biological-age estimate from your own bloods—shown as a range with honest coverage. Computed on-device. Your current estimate stays genuinely free. Lifetimer turns a blood panel you already have into a calm, transparent biological-age estimate—shown as a range, never false precision. AN HONEST ESTIMATE • Uses the published Levine 2018 PhenoAge equation. • Shows a biological-age range, coverage level, and exactly how many required markers you supplied. • Builds each estimate from one dated pathology panel—never a synthetic mix of different lab dates. • Suppresses the estimate below seven of nine required markers. • Explains disclosed population-reference assumptions for partial panels. YOUR DATA STAYS YOURS • Biomarkers and wellness signals remain on your device. • No account is required. • No ads, tracking, or third-party analytics. • Export your readings as CSV or erase local data at any time. FREE, FOR REAL • Unlimited manual biomarker entry. • Your current coverage-labelled PhenoAge estimate. • Weekly HRV, resting-heart-rate, VO₂ max, and sleep context from read-only Apple Health access. • Full methodology and citations. GO DEEPER WITH PRO • Signed per-marker model contributions with population reference ranges. • On-device, evidence-graded lifestyle ideas with citations and careful association language. • Longitudinal estimate trajectory and full history. • On-device lab PDF/photo scan with confirm-before-save editing. • A coverage-labelled provider summary for a clinician conversation. Lifetimer is a consumer wellness estimator and educational tracking aid, not a medical device. It does not provide a diagnosis, prognosis, treatment, or medical advice. Discuss lab results, supplements, and health decisions with a qualified clinician. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. The annual plan includes a 7-day free trial for eligible new subscribers, then renews at the displayed annual price. Manage or cancel in App Store account settings. Lifetime is a one-time purchase.

A clearer, more honest Lifetimer: • Biological age is now a coverage-labelled range; no estimate appears below 7 of 9 required markers. • Removed the placeholder cohort percentile. • Added signed model contributions with population references. • Estimates and provider summaries now use one dated lab panel; common US and Australian units are normalised before calculation. • Added on-device lab scan confirmation and editable OCR results. • Added cited, carefully hedged on-device lifestyle ideas. • Added CSV export, local reminders, a provider summary, and a range-based widget. • Pro now unlocks exactly the capabilities described on the paywall. • Updated privacy, terms, and support surfaces.
