Description

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
