Семейный фото-журнал атопии — теги по телу + триггеры + биологики, сводка для дерматолога одной кнопкой

Problem

Японские семьи с атопическим дерматитом (взрослые на Дупиксенте/Ринвоке/Цибинко + родители детей-атопиков 0-15 лет) делают сотни фотографий кожи в галерее телефона, но без тегирования по части тела, триггеру (диета/погода/стресс), фазе лечения. На приёме у дерматолога не могут показать «что было хуже на прошлой неделе и как реагирует на новый biologic».

Audience

Японские взрослые с умеренной/тяжёлой атопией на биологиках (Дупиксент 50-100k JPY/мес даже с NHI) + родители детей-атопиков 0-15 лет, тратящие 50k+ JPY/мес на лечение и нуждающиеся в семейном multi-account фото-таймлайне с триггер-аннотациями

What we ship

**Core features (MVP)**

  • Camera capture with 16-zone body-part tagger (front/back)
  • Trigger annotations: diet, weather (auto-pulled from JP 気象庁), stress, seasonal pollen
  • Treatment log: topical, oral, biologics (Dupixent monthly, Rinvoq daily, Cibinqo daily) with reminders
  • Multi-account family (1 parent + up to 3 child profiles, schema-isolated)
  • 90-day photo-timeline with treatment overlay
  • One-button PDF for dermatologist

**Primary user flow**

1. Dermatologist recommendation OR Twitter / note discovery

2. PWA install + E2E-encrypted R2 vault setup

3. First photo: tap body-zone → save → trigger tag suggestion

4. Day 7: 7-day photo strip visible → habit forms

5. Day 14: free trial ends → 1,200 JPY/month (cheap vs Dupixent 30-60k/month)

**What it looks like**

  • **Landing**: 「アトピーの『見せる』記録。家族で、皮膚科で。」 hero, family-photo ambience, dual CTA
  • **Main screen**: today tile + body-zone heatmap (last 30 days flares) + big `写真を追加` camera button
  • **PDF**: 4-page A4 — photo grid by body zone, treatment timeline, trigger correlations, narrative

**MVP build plan (12 days)**

  • Day 1-3: schema, R2 client-side encryption (libsodium-wrappers), JWT, PWA shell
  • Day 4-7: camera flow, body-zone tagger UI, trigger picker, family profile switcher
  • Day 8-10: timeline view, treatment overlay, JP weather API integration
  • Day 11-12: multi-page PDF, JA landing, deploy

Reasoning

Pain is real, recurring, AND financially validated — biologic patients spending 30-60k JPY/month make adherence/side-effect tracking economically rational. Atopiyo and Atopi Note exist but neither hits the family-private-multi-account + biologic-aware angle. Stack-fit is clean: PWA, R2, Postgres, Stripe — no native iOS push, no GPU/ML severity-scoring (which would be SaMD risk). Strict no-severity-AI guardrail keeps it strictly in logging space. Recurring-revenue fit excellent: chronic condition with daily treatment.

Quick competitive read

Market density: **medium** (5 named competitors, no direct overlap).

  • **Atopiyo** ([CMP-080-atopiyo](../competitors/CMP-080-atopiyo.md)) — JP-native, anonymous community/social feed, NOT private-family
  • **Atopi Note / Welby** ([CMP-080-atopi-note](../competitors/CMP-080-atopi-note.md)) — JP-native but Maruho-funded, pharma-bias on topical treatments
  • **Eczema Tracker / mwm.ai** ([CMP-080-eczema-tracker](../competitors/CMP-080-eczema-tracker.md)) — AI severity scoring (SaMD risk in JP), English-only
  • **MyEczemaTracker** ([CMP-080-myeczematracker](../competitors/CMP-080-myeczematracker.md)) — Western single-user, no biologic dose tracker, no JA
  • **LINE Healthcare** ([CMP-080-line-healthcare](../competitors/CMP-080-line-healthcare.md)) — general tele-derm consultation, no longitudinal photo log

**White space**: family-multi-account + biologic-aware (Dupixent/Rinvoq/Cibinqo dose tracker) + E2E-private + JA-native + dermatologist-PDF as primary loop + NO AI severity (避免 SaMD).

Initial pricing hypothesis

Free: 30 photos, single profile, 1 PDF/month. **Premium 1,200 JPY/month** or 12,000 JPY/year — small fraction of biologic medication cost.

Distribution hypothesis

1. JA SEO: 「アトピー 写真 記録」, 「デュピクセント 副作用 記録」 (low-comp long-tail)

2. Dermatology clinic QR-flyer (Stage 2)

3. X/Twitter JA in #アトピー #デュピクセント community

4. Stage 2: pharma patient-support program co-marketing
