Marker: Longevity Bloodwork

About

Marker is the longevity bloodwork log for people who track ApoB, not just LDL. Log your panel — ApoB, Lp(a), hsCRP, HbA1c, fasting glucose and insulin, triglycerides, total and HDL/LDL cholesterol — and Marker shows each value against a cited, named-author optimal range, then charts your trend over time. WHY MARKER IS DIFFERENT Most apps compare your labs to generic "reference ranges" — the bar for not being sick. Marker compares them to the optimal targets longevity-minded people actually aim for, and every single one names its source: • ApoB under 60 mg/dL — Peter Attia, Outlive • hsCRP under 1.0 mg/L — CDC/AHA • HbA1c & fasting glucose — ADA • Triglycerides, cholesterol, HDL, LDL — NCEP ATP III No "algorithm developed by our doctors." Named authorities you can look up yourself. WHAT YOU GET • A clean panel dashboard — every marker, your latest value, and where it sits • A trend chart for each marker with the optimal line drawn in • Frictionless entry — log a whole draw in one screen • Plain-English context for what each marker means • 100% private and offline — no account, no cloud, no ads PRICING Free to try for 48 hours. Unlock everything forever with a single purchase — no subscription, ever. Marker is an educational reference of published targets. It is not medical advice and does not diagnose. Always discuss your results with your physician.
