Marker turns your lab reports into a clear, private record you actually keep. Bring a report in four ways: • Open a PDF from Files • Share a PDF or image from another app • Snap a photo of a printed result • Type values in by hand Marker reads the report on your device and lays out each value next to the reference range that is printed on that same report — within range, above range, or below range, in plain descriptive words. No app-invented ranges, no scores, no verdicts. When a value looks uncertain, Marker flags the line and lets you check or correct it before anything is saved, so your history stays clean. Watch a value move over the years. Each marker opens into a timeline chart with the printed reference band drawn behind it, so you can see the shape of your own data across every report you have kept. Understand what you are looking at. For common markers — full blood count, the modern lipid panel including ApoB and Lp(a), liver, kidney, thyroid, and vitamins — Marker shows a short, plain-language description of what the value measures, with its source cited. Descriptions only; Marker does not tell you what to do. Private by design: • Everything stays on your iPhone • No account, no sign-in, no cloud • No content-reading analytics — your lab results stay on your device Marker is for informational use only and is not a medical device. It does not provide a diagnosis, medical advice, or treatment recommendations. Reference ranges come from your own lab report. Always talk to a qualified professional about your results. Read any report in full, for free. Keeping it — and building your history over the years — is Marker Pro. —— PAYMENT, RENEWALS, TERMS & PRIVACY Marker Pro is available as a Year Pass (12 months, one payment, no auto-renewal) or as a one-time Lifetime purchase. Prices are shown in the app and on the App Store. No subscription, no account.
