PressureOS

A complete blood pressure management planner in one private offline app. Seven tabs. One file. Yours forever for one price. A BP log that captures systolic, diastolic, and heart rate with time of day, arm used, and context tag (morning, evening, post-walk, stressed, post-meal) so you see what actually moves your numbers. Every reading is auto-classified using the AHA 2017 stages: Normal under 120/80, Elevated 120-129 over under 80, Stage 1 hypertension 130-139 over 80-89, Stage 2 hypertension 140 plus over 90 plus, and a Hypertensive Crisis alert above 180/120 that tells you to seek immediate care. A vanilla SVG 30-day trend graph plots three lines - sys, dia, HR - so you can see week-over-week direction at a glance. A DASH meal planner with a 1500 mg / 2300 mg sodium budget toggle, daily sodium running total, and 12 DASH-friendly recipe cards (oats with berries, lentil soup, salmon greens plate, chicken quinoa bowl, baked sweet potato, Mediterranean salad, veggie stir-fry, beans and rice, banana yogurt parfait, hummus veggie wrap, baked cod with herbs, white bean tomato stew). A triggers log with 7 quick-buttons (high sodium meal, stress, poor sleep, missed medication, alcohol, caffeine, intense exercise) plus a correlation insight that shows which triggers most often precede a Stage 1 or Stage 2 reading. A medication adherence tab with checkboxes per medication, with-food toggle, and a streak counter for each pill. A clinic visit tab to record the BP your doctor measured at the office vs your home average that week, with white-coat hypertension detection that flags you if clinic readings exceed home by 10 sys / 5 dia, and masked hypertension detection that flags the reverse pattern. A full reference table of sodium-rich foods to avoid (deli meats, canned soups, frozen meals, soy sauce, restaurant meals, condiments). Settings for custom targets, JSON export and import, full reset, and a 30-day demo seed showing improvement from Stage 1 down to Elevated. Every input saves locally to your device. Nothing goes to a server. No account, no subscription, no app store, no annual fee, no health data sold to advertisers. Works on laptop in any browser, and adds to your iPhone or Android home screen as a standalone app for offline use.
