Marker: Longevity Biomarker Log — Support

What Marker does

Marker is a private log for your longevity bloodwork. Enter your lab results — ApoB, Lp(a), hsCRP, HbA1c, fasting glucose and insulin, triglycerides, total cholesterol, HDL, and LDL — and Marker charts each value over time and shows it against a cited, named-author optimal range.

Common questions

How do I log my results? Tap “Log a draw,” pick the date, and enter the values you have — leave the rest blank. You can also add a single value from any marker's screen.

Where do the optimal ranges come from? Every range names its source (Attia's Outlive, CDC/AHA, ADA, NCEP ATP III). See “Sources & methodology” in Settings.

Is my data private? Yes — everything stays on your device. No account, no cloud, no tracking.

What does the purchase unlock? The 48-hour trial lets you try everything. A one-time $9.99 purchase unlocks logging new draws forever — no subscription.

I paid before and reinstalled. Open Settings → “Restore purchases.”

Important

Marker is an educational reference of published targets — not medical advice, and it does not diagnose. Always discuss your results with your physician.
