The lack of ranking data and the 818-day update gap suggest the app is currently in maintenance-mode rather than active growth. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all features - **Analysis:** The app is currently free with no visible subscription or IAP gates, limiting commercial sustainability. ## SWOT Analysis {#swot} **Core Strengths:** - Virtual shelf management provides a tangible inventory mechanism for physical book tracking. - Global database integration reduces manual entry friction for new book additions. **Growth Levers:** - Educational institution partnerships offer a B2B distribution channel for bulk library management. - Integration of social discovery features could convert the app into a community-driven reading hub. ## Recent Changes (v2 → v3) {#recent-changes} The product's strategic outlook has shifted from maintenance to potential sunsetting due to prolonged development inactivity. **Overall trend**: Declining **Compared at**: 2026-08-09 ### High-impact changes - **[Shifted] Strategic Outlook** (positioning) - **[Shifted] PM Action Item** (positioning) ### Medium-impact changes - **[Shifted] Competitive Threat Profile** (swot) ## What's New - **Latest (v8.0, 2 years ago):** Redesigned app screens and updated color palette. ## App Momentum (Zombie) {#momentum} - Ships no updates since May 2024. - Maintains 4.8 rating on 15 reviews. > **Cadence:** 1 total versions · 1 majors in last 6 months · 817 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Library Catalog is a book app that is completely free. It holds a 4.8/5 rating from 15 reviews. > **Bottom Line:** Library Catalog serves a clear utility for physical book organization, but the 818-day update gap suggests the developer has deprioritized the product, so the PM should evaluate whether to sunset the app or pivot to a B2B licensing model for libraries. **Best for:** Book collectors, bloggers, and educational institutions requiring personal or corporate library organization tools. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the app because the 818-day update gap indicates abandonment → reduce brand drag ### Outlook: Declining The book-cataloging market is consolidating around platforms that offer AI-driven recommendations and cloud-syncing, leaving static inventory tools exposed. Library Catalog's lack of development cadence suggests it will continue to lose relevance as user expectations for cross-platform integration rise. - 🔴 The 818-day update gap indicates the product is in maintenance-mode, which prevents it from competing with modern, AI-assisted cataloging tools. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.8/5 | | Total Reviews | 15 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Library Catalog** (this app) | 4.8/5 | N/A | Vladimir Yakushev | | [[박한평 문장집] 필사, 마음건강, 동기부여, 명언](https://marlvel.ai/apps/sproutgrowlabs-hanpyeong-free) | N/A/5 | N/A | SPROUTGROWLABS | | [옛글들 - 소설, 수필, 시](https://marlvel.ai/apps/app--383) | N/A/5 | N/A | kim juyoung | | [박한평 문장집 : 필사, 마음건강, 동기부여, 명언](https://marlvel.ai/apps/com-sproutgrowlabs-hanpyeong) | N/A/5 | N/A | SPROUTGROWLABS | | [두란노 비전통독](https://marlvel.ai/apps/app--969) | 3.3/5 | N/A | Duranno | | [스마트 성경과찬송가 - 피아노반주, 개역개정,새번역](https://marlvel.ai/apps/app--191) | 4.3/5 | N/A | Eugene Song | ## Company Profile - **Developer:** Vladimir Yakushev - **Website:** [https://mylibrary-264109.web.app](https://mylibrary-264109.web.app) ## Data Sources & Links - **App Store ID:** 1515907399 - **Dev Site:** [Official Website](https://mylibrary-264109.web.app) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*[박한평 문장집] 필사, 마음건강, 동기부여, 명언*](https://marlvel.ai/apps/sproutgrowlabs-hanpyeong-free) (SPROUTGROWLABS) · N/A Rating - [*옛글들 - 소설, 수필, 시*](https://marlvel.ai/apps/app--383) (kim juyoung) · N/A Rating - [*박한평 문장집 : 필사, 마음건강, 동기부여, 명언*](https://marlvel.ai/apps/com-sproutgrowlabs-hanpyeong) (SPROUTGROWLABS) · N/A Rating - [*두란노 비전통독*](https://marlvel.ai/apps/app--969) (Duranno) · 3.3/5 Rating - [*스마트 성경과찬송가 - 피아노반주, 개역개정,새번역*](https://marlvel.ai/apps/app--191) (Eugene Song) · 4.3/5 Rating - [*두플러스*](https://marlvel.ai/apps/app--972) (Duranno) · 4.8/5 Rating - [*생명의삶 정식버전*](https://marlvel.ai/apps/app--968) (Duranno) · 3.1/5 Rating - [*대한성서공회 연구성경*](https://marlvel.ai/apps/app--566) (Korean Bible Society) · 2.8/5 Rating - [*リビングバイブル*](https://marlvel.ai/apps/biblica-japanese) (Biblica) · 5.0/5 Rating - [*ジャンプルーキー！*](https://marlvel.ai/apps/com-shonenjump-rookie) (SHUEISHA Inc.) · 3.9/5 Rating ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
