<!-- section:executive-snapshot -->
## Executive Snapshot
**What it is:** 분노일기는 심리학 기법을 기반으로 감정을 기록하고 조절하도록 돕는 iOS용 감정 저널링 앱입니다.
**Why users hire it:** 사용자는 감정을 안전하게 쏟아내고 식히는 구조적 공간을 찾으며, 분노일기는 쿨다운 기능을 통해 충동적 반응을 억제하는 심리적 안전망을 제공합니다.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Differentiator] 60-minute Cool-down:** 기록 후 1시간 동안 접근을 제한하여 충동적 감정 반응을 방지합니다.
- **[Differentiator] Psychological Frameworks:** Pennebaker 글쓰기 및 CBT 기법을 통합하여 감정 정화의 전문성을 강화합니다.
<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

분노일기는 감정 관리 카테고리에서 심리적 기법을 강조하는 니치 도구로 포지셔닝하고 있습니다. 초기 출시 단계로, 범용 감정 기록 앱 대비 높은 전문성을 통해 차별화를 시도 중입니다.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Freemium
- **Tiers:** 광고 기반 무료 이용, 평생 이용권 구매
- **Analysis:** 광고 시청을 통해 쿨다운 등 기능적 제약을 우회하는 마이크로 트랜잭션 모델을 채택하고 있습니다.

<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- 60분 쿨다운은 충동적 감정 조절을 위한 독보적인 심리적 장벽을 형성합니다
- CBT 및 Pennebaker 기법 통합은 감정 정화의 전문성을 보장합니다

**Critical Frictions:**
- 초기 출시로 인한 리뷰 데이터 부재로 사회적 증명 부족
- 범용 감정 기록 앱 대비 낮은 사용자 커뮤니티 규모

**Growth Levers:**
- CBT 기반 심리 상담 연계를 통한 B2B 파트너십 확장

**Market Threats:**
- EMMO 등 범용 감정 기록 앱의 기능 업데이트로 인한 니치 시장 잠식

<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

The app's competitive positioning shifted from viewing its core friction as a liability to framing it as a clinical differentiator, accompanied by a move toward content-led growth.

**Overall trend**: Stable
**Compared at**: 2026-07-06

### High-impact changes
- **[Shifted] Outlook and Narrative Pivot** (positioning) — Outlook trend shifted from 'mixed' to 'stable', with the narrative moving from 'ad-gated cool-down is a disadvantage' to 'cool-down is a core psychological mechanism'.
- **[Shifted] SWOT Re-categorization** (swot) — The 60-minute cool-down moved from a 'weakness' (churn risk) to a 'strength' (psychological barrier); 'lack of social proof' was added as a new weakness.

### Medium-impact changes
- **[Shifted] PM Action Item Strategy** (positioning) — Decision shifted from 'Pivot' (A/B test cool-down duration) to 'Invest' (strengthen onboarding content to emphasize psychological value).
- **[Added] Updated Competitive Feature Gaps** (features) — Added 'Visual sentiment analysis' and 'Physical book export' as identified gaps against competitors.

<!-- section:rivals -->
## Rivals Landscape {#rivals}

> Competitive positioning identified by AI analysis of app features, category, and market signals.

### 분노일기 vs EMMO - 日记与笔记 — Head to Head
- **EMMO - 日记与笔记** by EMMO Corp.: EMMO dominates the emotional journaling space with a massive user base and high-frequency engagement, directly competing for the same 'mood-tracking' audience as 분노일기.
  - **Key differences:**
    - Massive established user community creates a strong network effect that our app currently lacks.
    - Highly polished, minimalist UI design sets a high aesthetic bar for emotional journaling apps.
    - Deeply integrated mood-tracking visualization provides long-term data insights that drive daily user retention.
  - **Where 분노일기 wins:**
    - ✅ Psychology-backed '60-minute cooldown' feature provides a unique, structured approach to anger management.
    - ✅ Clear, intentional 'discard' workflow helps users process negative emotions rather than just archiving them.
  - **Where EMMO - 日记与笔记 wins:**
    - ❌ Extensive market presence and high review volume establish significant social proof and brand trust.
    - ❌ Mature feature set supports broader note-taking needs beyond just emotional venting or anger management.
  - **Verdict:** Target should double down on its niche 'anger processing' identity to differentiate from EMMO's general-purpose journaling.

### Contenders (Strong Challengers)
- **[Shine - Timeline diary](https://marlvel.ai/apps/shine-timeline-diary)** by 晓松 高: Users report: uses data visualization and voice input to capture life stories, competing for users who want low-friction, high-insight journaling.
  - Story heatmap visualization provides an immediate, high-level overview of emotional trends over long periods.
  - Voice diary capabilities offer a lower-friction entry method for users who struggle with text-based venting.
- **[团纸日记-把生活写成一本书](https://marlvel.ai/apps/tuanzhiriji-benben)** by Shanghai Ningguang Information Technology Co., Ltd.: Targets the long-term archival value of journaling, positioning the app as a tool to create a physical-style book of life.
  - Physical book export functionality provides a tangible, high-value output that our digital-only app lacks.
  - Timeline view offers a superior retrospective experience for users looking to review their life history.
- **[iMood-心情日记、待办清单](https://marlvel.ai/apps/imood)** by 继伟 王: Overlaps by combining mood tracking with task management, targeting users who want to link their emotional state to productivity.
  - Integrated task management features allow users to correlate emotional states with daily productivity goals.
  - Customizable reminder system helps maintain consistent journaling habits through proactive user engagement prompts.
- **[一叶日记·极简卡片心情记录日记](https://marlvel.ai/apps/justtoday-diary)** by 荣九 蔡: Competes by offering a card-style interface that simplifies the journaling experience, appealing to users who prefer quick, visual entries.
  - Card-style interface allows for faster, more digestible daily entries compared to our long-form focus.
  - Robust WebDAV and iCloud sync options offer users more flexibility in data ownership and backup.

### Peers (What They Do Better)
- **Chat with Me: Selfcare Journal** by Jun Haeyun: Uses a chat-based interface to promote self-care, directly mirroring the 'venting' use case of our target app.
  - Chat-first UX mimics messaging apps, making the journaling process feel more natural and less formal.
  - Self-care focused prompts provide immediate emotional support, contrasting with our app's focus on anger release.
- **MyMemoir AI** by Jason Liang: Leverages AI to automate the biography-writing process, competing for users interested in legacy and reflection.
  - Automated AI prompts guide users through specific life milestones to build a comprehensive personal biography.
  - Structured data organization ensures that memories are categorized and easily searchable for future reference.
- **时光之语** by Beijing Haixin Intelligence Technology Co., Ltd.: Focuses on memoir-style documentation, appealing to users who want to curate their life experiences into a narrative.
  - Narrative-focused structure encourages users to build a cohesive life story rather than just venting emotions.
  - Simplified, clean interface reduces cognitive load for users focused on long-term memory preservation.
- **[Ondo: AI Journal](https://marlvel.ai/apps/ondo-ai-journal)** by Onda Labs, Inc.: Uses AI to facilitate conversational journaling, shifting the user experience from self-reflection to interactive dialogue.
  - Conversational AI interface provides active feedback, acting as a digital therapist rather than a passive log.
  - AI-generated postcards turn daily entries into shareable, visual artifacts, increasing the app's viral potential.

### New Kids on the Block (What's Innovative)
- **[Lore: Every Chat Hides a Story](https://marlvel.ai/apps/lore-every-chat-hides-a-story)** by Amon Studio: Integrates with messaging apps to turn daily chats into stories, capturing the 'passive journaling' market.
  - WhatsApp chat integration allows for effortless, automatic journal entry creation without manual typing requirements.
- **[おうち新聞](https://marlvel.ai/apps/karmait-ouchishinbun)** by Ide Koshin: Introduces a unique 'family newspaper' format that gamifies the journaling process for household members.
  - Automated weekly newspaper generation creates a fun, collaborative family experience that differentiates from individual journaling.

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

분노일기 is an established lifestyle app that is free with in-app purchases.

<!-- speakable-start -->
> **Bottom Line:** 분노일기는 심리학적 기법을 활용한 감정 조절이라는 명확한 가치를 제공하지만, 초기 사용자 확보를 위한 사회적 증명이 부족하므로 핵심 기능인 쿨다운의 심리적 효과를 강조하는 마케팅을 우선해야 합니다.
<!-- speakable-end -->

**Best for:** 구조적이고 심리학적으로 검증된 감정 조절 도구를 찾는 개인 사용자.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [INVEST] [HIGH IMPACT] 심리적 효과를 강조하는 온보딩 콘텐츠를 강화하여 초기 사용자 유입을 유도합니다 — *리뷰 데이터 부재로 인한 사회적 증명 부족을 심리적 전문성 강조로 보완해야 합니다* _(trade-off: deprioritize 기존 기능의 UI 개선 작업을 차분기로 연기합니다)_
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors

- 시각적 감정 트렌드 분석 (EMMO에서 제공하지만 분노일기에는 부재)
- 물리적 도서 출력 기능 (团纸日记에서 제공하지만 분노일기에는 부재)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Stable

감정 관리 시장은 범용 기록 앱과 전문 심리 도구로 양분되고 있습니다. 분노일기는 후자의 포지션을 점유하고 있으며, 향후 사용자 데이터가 축적됨에 따라 심리적 효용을 입증하는 것이 성장의 핵심입니다.

- ⚪ 초기 출시 단계로, 심리 기법 기반의 기능적 차별화가 시장에서 어떻게 수용될지 지켜봐야 합니다.
