Marker is the longevity bloodwork log for people who track ApoB, not just LDL. Log your panel โ€” ApoB, Lp(a), hsCRP, HbA1c, fasting glucose and insulin, triglycerides, total and HDL/LDL cholesterol โ€” 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" โ€” 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: โ€ข ApoB under 60 mg/dL โ€” Peter Attia, Outlive โ€ข hsCRP under 1.0 mg/L โ€” CDC/AHA โ€ข HbA1c & fasting glucose โ€” ADA โ€ข Triglycerides, cholesterol, HDL, LDL โ€” NCEP ATP III No "algorithm developed by our doctors." Named authorities you can look up yourself. WHAT YOU GET โ€ข A clean panel dashboard โ€” every marker, your latest value, and where it sits โ€ข A trend chart for each marker with the optimal line drawn in โ€ข Frictionless entry โ€” log a whole draw in one screen โ€ข Plain-English context for what each marker means โ€ข 100% private and offline โ€” no account, no cloud, no ads PRICING Free to try for 48 hours. Unlock everything forever with a single purchase โ€” 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.
