Marker compares them to the optimal targets longevity-minded people actually aim for, and every single one names its source:\n• ApoB under 60 mg/dL — Peter Attia, Outlive\n• hsCRP under 1.0 mg/L — CDC/AHA\n• HbA1c & fasting glucose — ADA\n• Triglycerides, cholesterol, HDL, LDL — NCEP ATP III\n\nNo \"algorithm developed by our doctors.\" Named authorities you can look up yourself.\n\nWHAT YOU GET\n• A clean panel dashboard — every marker, your latest value, and where it sits\n• A trend chart for each marker with the optimal line drawn in\n• Frictionless entry — log a whole draw in one screen\n• Plain-English context for what each marker means\n• 100% private and offline — no account, no cloud, no ads\n\nPRICING\nFree to try for 48 hours. Unlock everything forever with a single purchase — no subscription, ever.\n\nMarker is an educational reference of published targets. It is not medical advice and does not diagnose. Always discuss your results with your physician.","facts":{"developer_id":1635315269,"developer_url":null,"first_released":"2026-06-16T07:00:00Z","support_url":"https://daria-kopaliani.github.io/moondog/marker/support.html","privacy_url":"https://daria-kopaliani.github.io/moondog/marker/privacy.html","website_url":null,"app_version":"1.2","release_notes":"Maintenance update.
