PatternMD is a free, anonymous symptom tracker and chronic illness journal. Log migraines, flares, pain, fatigue, anxiety, long COVID, fibromyalgia, endometriosis, lupus, IBS, PTSD or any symptom in seconds, discover what triggers it, and connect with people who feel exactly what you feel — without ever revealing who you are. You are not alone in this. WHAT PATTERNMD DOES Log your symptoms. Track headaches, fatigue, anxiety, joint pain, brain fog, nausea, insomnia — anything. Add an optional trigger note like "ate dairy" or "barely slept." It takes 10 seconds. Say ME TOO. Tap ME TOO on any community post that matches your experience. The more people who say it, the clearer the pattern becomes — and you instantly see you are not the only one. Talk to Alyssa. Alyssa is our in-app AI companion. Type a message and she will help you put words to what you're feeling, reflect on a pattern in your logs, or route you to a crisis resource if you need one. Alyssa is a support tool, not a doctor — she does not diagnose, treat, or prescribe. Discover your patterns. The Pattern Engine analyzes your logs against the entire community to surface real insights: Top community-reported triggers Time-of-day and day-of-week patterns Environmental correlations — weather, air quality, and pollen Severity escalation alerts Personalized recommendations Automatic cross-language search across all four languages Public or private. Every symptom you log can be Public, so the community can say ME TOO, or Private, so it stays in your journal, your patterns, and your connected doctor's view only. Private journal. Keep a private health diary alongside your community posts. Your journal is yours alone and never visible to anyone else. Medication tracking. An optional private medication list with dosage, frequency, and notes. Only you — and your connected provider, if you choose — can see it. Connect to your doctor. Optionally share your tracked data with a verified healthcare provider through the secure Provider Portal. You stay in control and can connect or disconnect anytime. Pediatric posts. Parents and legal guardians can log symptoms on behalf of a child in their care. Posts are clearly marked, and the child never has an account. TAPMD wellness games. Two science-backed mini-games — MedMatch and BrainRx — help reduce stress and anxiety, with a bonus of medical-terminology learning. WHY PATTERNMD IS DIFFERENT 100 percent anonymous. You get a PMD-XXXXXXXX ID. No name, no photo, no real-world identity ever shown. Multilingual. Full support for English, Spanish, German, and Vietnamese, with automatic cross-language translation and search across all four. No targeted ads. Sponsored posts are clearly labeled and never use your personal data. HIPAA-aligned security. Encrypted storage, row-level access controls, and data minimization. Never sold. Your email and data are never sold to anyone, ever. WHO PATTERNMD IS FOR People living with chronic conditions. Migraine sufferers. People with fatigue, fibromyalgia, long COVID, anxiety, autoimmune conditions, or unexplained symptoms. Parents tracking pediatric symptoms. Service members and veterans. Anyone who has ever felt "I just want to know if anyone else feels this too." You are not crazy. You are not making it up. Your symptoms have patterns. Let us find them together. IMPORTANT PatternMD does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider for medical decisions. If you are in crisis, call 988 (US, 24/7, free and confidential) or your local emergency services immediately. PatternMD is for adults 18 and older only. Questions? Email contact@patternmd.app

Tired of jumping between 3 apps to track one body? Zebra is a calm symptom tracker for people managing POTS, EDS, and Fibromyalgia. Track flares, symptoms, medications, salt, water, triggers, notes, and orthostatic vitals in one iPhone app, then turn your recent history into a doctor-ready PDF. Built for invisible illness, brain fog, and the appointment scramble. TRACK WHAT MATTERS Zebra helps you capture the pieces that are hardest to remember later: Daily flare severity, duration, and notes POTS, EDS, and Fibromyalgia symptom check-ins Salt and water tracking Medication entries Trigger notes Orthostatic vitals: lying, standing, and recovery heart rate and blood pressure Trends across your recent history GUIDED ORTHOSTATIC TESTS Use Zebra's step-by-step orthostatic flow to track heart rate and blood pressure while lying, standing, and during recovery. Enter readings manually or, when available, use HealthKit support for heart-rate capture. PROOF FOR YOUR DOCTOR When an appointment is coming up, Zebra can export a 30-day doctor report PDF with your flares, symptoms, medications, salt, water, triggers, notes, and orthostatic summaries. No more digging through Notes, screenshots, and memory the night before a visit. MADE FOR BAD DAYS Zebra is designed to be fast, gentle, and low-friction. Use curated symptom lists instead of building a tracker from scratch. Track what happened, leave optional details for later, and skip the guilt. Missing days do not erase your history. PRIVATE BY DESIGN Your health history is sensitive. Zebra is built as a native iPhone app using Apple's health and data frameworks. You stay in control of what you track and what you choose to share. FREE TO TRACK. PREMIUM FOR DEEPER HISTORY. Start with core tracking for flares, symptoms, medications, salt, water, triggers, notes, trends, and orthostatic vitals. Zebra Premium adds expanded history and doctor-report access for users who want more appointment support. Zebra is for people with POTS, EDS, and Fibromyalgia who want less app-juggling, clearer history, and proof they can bring to a doctor. Zebra does not diagnose, treat, or replace medical care. It helps you organize and share your own tracked history. Privacy Policy: https://zebratracker.app/privacy Terms of Use: https://zebratracker.app/terms
