The lack of recent updates (197 days) suggests a maintenance-mode posture that contrasts with the active feature-expansion typical of category leaders. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier: up to 100 books, 3 AI shelf scans, Premium tier: $4.99/month for unlimited books, unlimited scans, and statistics - **Analysis:** The freemium model uses volume caps on AI scanning and total book count to drive conversion to a $4.99/month subscription. ## SWOT Analysis {#swot} **Core Strengths:** - AI-powered spine scanning provides a defensible barrier for rapid library digitization. - Goodreads CSV import lowers switching costs for established readers. **Growth Levers:** - Adding social sharing features could leverage the existing library data to increase organic acquisition. ## App Momentum (Zombie) {#momentum} - Last major release 197 days ago. - Development velocity currently stalled. > **Cadence:** 1 total versions · 0 majors in last 6 months · 197 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Shelves - Home Library Manager is a reference app that is free with in-app purchases. > **Bottom Line:** Shelves provides a high-utility digitization tool, but the 197-day update gap creates a significant churn risk for power users. Prioritizing a stability release would stabilize the user base before attempting to scale the premium subscription tier. **Best for:** Book collectors and readers who want to digitize physical libraries and track reading progress. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Ship a stability update because the 197-day release gap creates a churn risk for power users → stabilize retention. ### Outlook: Declining The library management category is shifting toward community-integrated platforms, leaving Shelves exposed due to its lack of recent updates. Without a return to active development, the app risks losing its core user base to more frequently updated competitors. - 🔴 The 197-day release gap indicates a stalled development cadence, which erodes user trust in the app's long-term viability. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Shelves - Home Library Manager** (this app) | N/A/5 | N/A | Silent Planet LLC | | [올어바웃성경](https://marlvel.ai/apps/com-allabout-bibleapp) | 5.0/5 | N/A | Gilju Lee | | [Hallow: Prayer & Meditation](https://marlvel.ai/apps/hallow-prayer-meditation) | 4.7/5 | n/a | Hallow, Inc. | | [고려대 한국어 속담 사전](https://marlvel.ai/apps/app--428) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [우리말 의학사전](https://marlvel.ai/apps/app--427) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [공인중개사 용어사전](https://marlvel.ai/apps/app--429) | N/A/5 | N/A | DaolSoft, Co., Ltd. | ## Company Profile - **Developer:** Silent Planet LLC - **Website:** [https://silentplanet.app/shelves](https://silentplanet.app/shelves) ## Data Sources & Links - **App Store ID:** 6757828544 - **Dev Site:** [Official Website](https://silentplanet.app/shelves) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*올어바웃성경*](https://marlvel.ai/apps/com-allabout-bibleapp) (Gilju Lee) · 5.0/5 Rating - [*Hallow: Prayer & Meditation*](https://marlvel.ai/apps/hallow-prayer-meditation) (Hallow, Inc.) · 4.7/5 Rating - [*고려대 한국어 속담 사전*](https://marlvel.ai/apps/app--428) (DaolSoft, Co., Ltd.) · N/A Rating - [*우리말 의학사전*](https://marlvel.ai/apps/app--427) (DaolSoft, Co., Ltd.) · N/A Rating - [*공인중개사 용어사전*](https://marlvel.ai/apps/app--429) (DaolSoft, Co., Ltd.) · N/A Rating - [*브리태니커 콘사이스 백과사전*](https://marlvel.ai/apps/app--425) (DaolSoft, Co., Ltd.) · N/A Rating - [*100 Radio Hrvatska (HR) : Vijesti, glazba, Nogomet*](https://marlvel.ai/apps/100-radio-hrvatska-hr-vijesti-glazba-nogomet) (Thomas Gesland) · 1.0/5 Rating - [*100 US Citizenship Test Questions 2017*](https://marlvel.ai/apps/100-us-citizenship-test-questions-2017) (Andrey Fetisov) · 4.7/5 Rating - [*١٠١ پرسیار لە زانستی قورئان*](https://marlvel.ai/apps/app--952) (Abdulwahab F.
