iOS에서 독서관리(책 읽은 기록, 진도 추적, TBR 관리, 독서 통계, 감상 노트 등)로 유명하고 실제로 많이 쓰이는 앱 5가지를 현재(2026년) 기준으로 정리해 볼게요.

1. 북모리 (Bookmory)
   한국 사용자들 사이에서 압도적으로 인기 많음. 감성적인 디자인, 예쁜 기록 화면, 독서 캘린더, 인상구절 정리, 책 더미 시각화 등으로 SNS 공유용으로도 최고. 한국어 완벽 지원.

2. 북트리 (BookTree)
   국내에서 가장 오래되고 안정적인 독서관리 앱 중 하나. 독서 달력, 하이라이트 정리, 통계, PDF 내보내기 등 기능이 탄탄함. 한 번 구매로 iPhone/iPad/Mac 모두 사용 가능.

3. StoryGraph
   2025~2026년에 Goodreads 대체 앱으로 가장 급부상한 앱. 상세한 독서 통계·그래프·무드 분석·페이스 추적 등이 압도적. 데이터 덕후들에게 특히 추천. iOS 앱도 깔끔하게 잘 나옴.

4. Bookly
   타이머 기반 실시간 독서 추적의 원조 격. 읽는 시간·페이지 속도·목표 달성률·습관 형성에 특화. 배경음악 기능도 있어서 집중 독서할 때 좋음. 전 세계적으로 오랫동안 인기.

5. Goodreads
   여전히 전 세계 독서인들이 가장 많이 쓰는 클래식 앱. 책 검색·리뷰·별점·TBR·연간 목표·친구 독서 기록 공유 기능이 가장 방대함. Amazon 소유라 책 정보도 가장 풍부.

추가 팁
- 감성·디자인 중시 → 북모리
- 통계·데이터 분석 → StoryGraph
- 습관·타이머 중심 → Bookly
- 한국어 책 위주 오래된 기록 → 북트리
- 소셜·리뷰·전 세계 책 정보 → Goodreads

이 중에 본인 스타일에 제일 맞는 거 하나만 골라서 써보는 걸 가장 추천해요! 😄

Product Requirements Document (PRD) for "ReadMaster" - The Ultimate Reading Management App

1. Document Information

• Document Title: PRD for ReadMaster App
• Version: 1.0
• Date: January 29, 2026
• Author: Grok AI (based on integration of features from Bookmory, BookTree, StoryGraph, Bookly, and Goodreads)
• Purpose: This PRD outlines the requirements for developing "ReadMaster," a comprehensive iOS-exclusive reading management app that combines and complements the best features from five leading apps: Bookmory (aesthetic and social sharing), BookTree (stable tracking and export), StoryGraph (advanced analytics), Bookly (habit-building timers), and Goodreads (vast database and community). The goal is to create a "best-of-all-worlds" app that addresses gaps in individual apps, such as limited social integration in analytics-focused ones or lack of real-time tracking in database-heavy apps.

2. Product Overview

2.1 Executive Summary

ReadMaster is an iOS app designed to be the ultimate tool for book lovers, integrating seamless reading tracking, advanced analytics, habit formation, aesthetic visualization, and social/community features. By complementing the strengths of existing apps:
- Bookmory's aesthetics with StoryGraph's data depth for visually appealing yet insightful dashboards.
- Bookly's timers with BookTree's export tools for practical habit tracking and data portability.
- Goodreads' database with all others for a robust, user-friendly ecosystem.

This results in a unified app that minimizes the need for multiple tools, enhancing user retention through personalization, gamification, and cross-device sync (iPhone, iPad, Mac via iCloud).

2.2 Problem Statement

Existing reading apps excel in niches but lack comprehensiveness:
- Users switch apps for aesthetics (Bookmory) vs. analytics (StoryGraph).
- Habit tracking (Bookly) often misses social sharing (Goodreads) or detailed mood analysis (StoryGraph).
- Data export (BookTree) is underutilized without integrated timers or visualizations.

ReadMaster solves this by creating a holistic platform, reducing fragmentation and improving user experience.

2.3 Product Goals

• Primary Goal: Provide an all-in-one reading management solution that boosts engagement, retention, and reading habits.
• Secondary Goals:
• Achieve 4.8+ App Store rating within 6 months of launch.
• Support 1M+ downloads by end of 2026.
• Monetize via freemium model (free core features; premium for advanced analytics and exports).

2.4 Success Metrics

• User engagement: Average daily active users (DAU) > 50% of monthly active users (MAU).
• Retention: 30-day retention rate > 60%.
• Feature adoption: >70% users utilizing at least 3 integrated features (e.g., timer + analytics + sharing).
• Feedback: NPS score > 70.

3. Target Audience and User Personas

3.1 Target Audience

• Primary: Avid readers aged 18-45, including students, professionals, and book club members, primarily in Korea and English-speaking markets (due to Bookmory/BookTree's Korean focus and others' global appeal).
• Secondary: Casual readers seeking habit formation; authors/bloggers for review tools.
• Market Size: Global reading app market projected at $5B+ by 2027; focus on iOS users (40% of smartphone market).

3.2 User Personas

1. Aesthetic Enthusiast (e.g., from Bookmory): 25-year-old female, loves visually sharing reading progress on SNS. Needs pretty dashboards and easy exports.
2. Data Nerd (e.g., from StoryGraph): 30-year-old male, tracks stats obsessively. Wants mood analysis, graphs, and pace predictions.
3. Habit Builder (e.g., from Bookly): 35-year-old professional, uses timers for daily reading goals. Seeks integration with background music and reminders.
4. Community Lover (e.g., from Goodreads): 28-year-old book club member, shares reviews and TBR lists. Desires friend syncing and vast book database.
5. Practical User (e.g., from BookTree): 40-year-old, values stability and PDF exports for long-term records.

4. Functional Requirements

Features are prioritized as Must-Have (M), Should-Have (S), or Could-Have (C). Integrated from the five apps to complement each other.

4.1 Core Features

• Book Discovery and Database (from Goodreads + all) (M):
• Search/integration with Amazon/ISBN databases for millions of books (Korean/English support).
• Add books via scan, search, or manual entry; auto-populate covers, summaries, genres.

• TBR (To-Be-Read) shelves with sorting (by mood, length, author).

• Reading Tracking and Timers (from Bookly + BookTree) (M):

• Real-time timer for tracking reading sessions, page speed, and total time.
• Progress tracking: % complete, pages read, estimated finish date.

• Habit streaks, daily/weekly goals with notifications and gamification (badges).

• Analytics and Insights (from StoryGraph + BookTree) (M):

• Detailed stats: Reading speed, total books/time per year, genre/mood breakdowns.
• Graphs/charts: Mood analysis (e.g., "uplifting" vs. "dark" books), pace trends.

• Predictive insights: "Based on your speed, finish this book in 5 days."

• Aesthetic Visualization and Notes (from Bookmory + BookTree) (M):

• Customizable dashboards: Book stacks, calendars with color-coded progress.
• Highlight/quotes organizer with tags, search, and export to PDF/CSV.

• Sensual UI: Themes (light/dark/aesthetic modes), animations for progress updates.

• Social and Sharing (from Goodreads + Bookmory) (M):

• Friend/follow system: See others' reading activity, shared TBRs, group challenges.
• Reviews/ratings: Post reviews, see aggregated scores, integrate with SNS (Instagram/Twitter sharing of pretty screenshots).
• Community forums or book clubs within app.

4.2 Complementary Integrations

• Cross-Feature Synergies:
• Timer data feeds into analytics (e.g., Bookly timers populate StoryGraph-style graphs).
• Aesthetic shares include stats (e.g., Bookmory visuals with BookTree exports).
• Database enhances all: Goodreads search powers Bookmory's pretty shelves.
• Additional Enhancements (S):
• Background music/ambient sounds during timers (from Bookly).
• AI recommendations: Suggest books based on mood analysis and past reads.
• Offline mode: Sync via iCloud for iOS/macOS (from BookTree).

4.3 User Flows

2. Daily Use: Start timer, update progress, view dashboard.
3. Social: Share progress, join challenges.
4. Export/Analysis: Generate yearly PDF report with graphs.

5. Non-Functional Requirements

5.1 Performance

• Load time: <2 seconds for dashboards.
• Sync: Real-time via iCloud; handle up to 10,000 books per user.

5.2 Usability

• Constraints: Budget for development (~$500K); team of 5 devs/designers; 6-month timeline.

7. Risks and Mitigations

• Risk: Feature overload leading to bloated app. Mitigation: Prioritize MVPs; user testing for UX.
• Risk: API changes (e.g., Goodreads). Mitigation: Build fallback local database.
• Risk: Competition from updates to existing apps. Mitigation: Focus on unique integrations; patent key features.
• Risk: Privacy concerns. Mitigation: Transparent policies; opt-in for social.

8. Appendix

• Wireframes/Sketches: (To be developed in design phase; e.g., dashboard combining Bookmory visuals with StoryGraph charts.)
• Monetization: Freemium – Premium ($4.99/month) for unlimited exports, AI insights, ad-free.
• Next Steps: Conduct user surveys; prototype core features; beta test with 100 users.
