## Description

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.
