Tap once, speak in the dark — your migraine log writes itself, then shows the trigger combo nobody told you about.
Problem
Migraine sufferers can't type 15+ fields into trackers like Migraine Buddy mid-attack — light hurts, nausea blocks scrolling — yet that data is exactly what neurologists need. After months of paper logs they still see only single-axis insights ('weather affected you 12 times'), never the combined fingerprint ('barometric drop + day-14 of cycle + <5h sleep').
Audience
US women 25-55 with chronic migraine (3+ attacks/month), already cycled through Migraine Buddy / MiG / Cephra and abandoned them, prepping for $250 neurologist visits with patchy memory data

- SIG-20260426-us-health-companion-migraine-voice-log-during-attack: "With Migraine Trail, just speak. Our Voice AI logs your symptoms, triggers, and duration instantly—so you can focus on feeling better."
- SIG-20260426-us-health-companion-migraine-multi-trigger-correlation-gap: "we score your suspected triggers so you can see how they correlate with your symptoms. It's a game changer."
What we ship
**Core features (MVP)**
- **Single-button voice log**: dark screen, one giant button, tap → 30s recording → Whisper → auto-tags (severity, location, aura, meds, what you were doing). User confirms tags with one tap.
- **Auto-context**: every log auto-attaches barometric pressure (OpenWeather by location), sleep (Apple Health), cycle day (Apple Health / Clue / manual).
- **Weekly correlation report**: "Top-3 trigger combos: barometric drop + sleep <6h (12 matches), cycle day 14-15 + caffeine (8 matches)". Pure statistics, no AI diagnosis.
- **Doctor PDF**: one click → single-page PDF: attack count over period, day-of-week distribution, top-5 trigger combos, medication log. User prints, brings to neurologist.
- **Anti-features (critical)**: NO "here's what you have", NO "tomorrow you'll have an attack" predictions, NO medication recommendations.
**Primary user flow**
1. Email signup, pick: "chronic / episodic / newly diagnosed".
2. 3-screen onboarding: barometric pull permission (location), optional Apple Health (sleep + cycle).
3. Attack hits → open app, tap, say "level 7, left temple, aura ~5 min, took sumatriptan" — log saved.
4. Weekly push: "you had 3 attacks, here are correlations" → opens weekly report.
5. Free: 5 logs/month, basic correlation. Pro $7.99/mo: unlimited logs, multi-axis correlation, doctor PDF, Apple Health import.
**What it looks like**
- **Landing**: "Voice your migraine. We do the math." hero, screenshot of giant button on dark field, quote "I can't type when my head's exploding."
- **Main app screen**: 90% surface = one big red button "I'm having one". Below: counter "12 days since last attack".
- **Weekly report**: 3 trigger-combo cards with match count and horizontal time-axis sparkline.
**MVP build plan (11 days)**
- Day 1-3: Postgres schema (attacks, tags, weather snapshots), FastAPI, Stripe wiring, Whisper client.
- Day 4-6: tag extraction prompt (structured JSON), OpenWeather auto-pull, Apple Health PWA bridge.
- Day 7-8: correlation engine (sliding-window confidence scoring — simple statistics, not ML).
- Day 9-10: PDF generator, paywall, dark-mode polish.
- Day 11: landing, deploy, launch on r/migraine.
Reasoning
The dual pain is captured in SIG-multi-trigger-correlation-gap and SIG-voice-log-during-attack: patients abandon existing apps precisely because (a) logging during an attack is physically impossible and (b) nobody surfaces multi-axis correlations. Migraine Buddy (3M+ installs) suffers from both — fragmented onboarding, manual 15-field input, single-axis "view trends". Newer entrants (Migraine-AI, Migraine Insight, CalmGrid, Migraine Trail) market either voice-log OR multi-axis correlation, but none combine both + doctor PDF in one focused utility. Regulatory safety: we do NOT diagnose, NOT predict, NOT recommend medications — just a structured log + statistics on user-supplied data + a PDF for the user's own use. Lesson from IDEA-047: AI extracts only what the user said (their own words → tags), never interprets or summarizes medical facts.
Quick competitive read
- **Migraine Buddy** (Healint, 3M+ installs) — leader by reach, but manual entry, single-axis insights, no voice. Their audience is our audience.
- **Migraine Trail** — voice-first, but newly launched, no multi-trigger correlation engine.
- **Migraine-AI / CalmGrid** — multi-axis marketing, but manual entry and no voice.
- **Cephra / MiG** — neurologist-positioned, focused on med log, not trigger correlation.
- **White space**: medium (4-5 direct competitors, nobody combines voice + multi-axis + dark mode + doctor PDF in one focused utility). Score hint: competitive_pressure 5-6.
Initial pricing hypothesis
Free: 5 logs/month + basic weekly correlation. Pro: $7.99/mo or $59/yr — unlimited logs, multi-axis correlation, neurologist PDF, Apple Health/Google Fit integration, CSV export. Roughly half the price of Migraine Buddy Premium ($14.99/mo) — pricing is the wedge.
Distribution hypothesis
1) **r/migraine + r/ChronicMigraine** — solo-dev "Built voice-first migraine tracker because I couldn't type during attacks. Free for community." Authenticity wins.
2) **TikTok #MigraineLife** — short demo "Look at this giant button. Just speak. Done." High viral potential.
3) **Neurologist office QR codes** — outreach to 50 small private neuro-practices, free 6-month Pro to practice manager in exchange for waiting-room flyer.
