Blood Test Tracker

Features
Read full description

Every blood test you have ever taken, in one place — logged, flagged against its reference range, and charted over time. LabResults is a blood test tracker and bloodwork logbook: type in each result exactly as printed on your lab report and watch every biomarker build into a timeline you can bring to your doctor. LabResults is deliberately a transcription log, not an interpreter. It has no built-in reference database, because reference intervals differ between laboratories and assays — the only correct source is the range printed on your own report. You enter the value and the range; the app does the remembering, the flagging and the charting. It never suggests a cause and never recommends an action. WHAT YOU GET • Open the app and instantly see which of your latest results sit outside their reference range — LOW in orange, HIGH in red — instead of digging through paper reports and portal PDFs • A trend chart for every test: watch your LDL move across three draws, with your lab's own low and high lines drawn straight onto the chart • Log a whole panel in minutes — value, unit, reference range, lab name, date and notes, exactly as the report prints them • One-sided ranges handled honestly: "< 200" or "> 40" stays one-sided, so flags never lie • Show glucose or cholesterol in mg/dL or mmol/L when different labs report in different units — your stored numbers never change • A CSV export of your complete history, ready to print or hand over at your next appointment PERFECT FOR • Anyone following cholesterol, blood sugar, HbA1c, TSH or vitamin D across repeat panels • Patients whose results are scattered across paper reports and several lab portals • People preparing for a doctor's visit who want the whole history on one page • Annual-checkup people who want this year's panel next to last year's WHY NOT JUST THE PATIENT PORTAL? A portal shows one provider's results, in that provider's format, for as long as they keep them. LabResults holds every draw from every lab — including paper reports the portal has never seen — in one timeline that lives on your phone and answers to you. PRIVATE BY DEFAULT Everything you enter is stored in a database on your device. No account, no analytics, no advertising, and no network traffic beyond Apple's own purchase and restore calls. A CSV leaves the phone only when you choose to share it. LabResults is for personal tracking only and is not medical advice. It never interprets a result — always discuss your results, especially out-of-range ones, with your doctor. FULL ACCESS LabResults requires Full Access to use the app: a Weekly or Yearly auto-renewing subscription, or a one-time Lifetime purchase. Every plan unlocks everything — logging, out-of-range flags, trend charts and CSV export. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings. Download LabResults and log your latest panel tonight — the next time your doctor asks "what was it last time?", you will have the answer in your pocket.

About

Marker · Blood Test Tracker

Features
Read full description

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.
