US Market. No publisher influence. > **Key Insight:** Design Pattern Reference is a reference app by 强 马. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Reference | | **Developer** | 强 马 | | **Pricing** | Paid | | **Platforms** | iOS | | **Confidence** | Low (0.15/1.0) | | **Data Age** | 39d | ## Metadata & Market Performance - **Publisher:** 强 马 - **Category:** Reference - **Target Audience:** Software developers and computer science students requiring offline access to standard design pattern definitions. - **Platforms:** iOS - **Version Reviewed:** 18.2 - **Report Date:** 2026-08-23 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.15/1.0) - **App Store ID (iOS):** 946885365 - **Bundle ID:** job.test.designpattern - **Performance Trend:** Stable - **Data Window:** Analysis based on signals collected up to 2026-08-23 ## Executive Snapshot **What it is:** Design Pattern Reference is a static, offline-first library of 23 software design patterns for developers and students on iOS. **Why users hire it:** It removes the dependency on internet connectivity for developers needing quick access to standard architectural patterns during offline coding sessions. ## App DNA (Features & Intent) - **[Standard] Design Pattern Catalog:** Library of 23 standard patterns categorized by Creational, Structural, and Behavioral domains. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. ## Market Position {#market-position} Design Pattern Reference occupies a static utility niche, priced at $1.99. Its 19-month update silence contrasts with the evolving nature of software documentation, limiting its competitive relevance. ## Monetization Strategy - **Model:** Paid - **Tiers:** $1.99 one-time purchase - **Price:** iOS: $1.99 - **Analysis:** Paid model targets users preferring a one-time cost for permanent, offline access over ad-supported or subscription-based web alternatives. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first architecture removes connectivity dependencies **Growth Levers:** - Adding code-snippet copy-paste functionality increases utility ## What's New - **Latest (v18.2, 1 years ago):** General maintenance and content updates. ## App Momentum (Zombie) {#momentum} - No feature updates for 19 months. - Maintains static offline reference library. > **Cadence:** 1 total versions · 0 majors in last 6 months · 577 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Design Pattern Reference is a reference app that is a paid app. > **Bottom Line:** Design Pattern Reference provides a stable, offline-first reference, but the lack of updates since early 2025 leaves it vulnerable to free, living web documentation. The PM should sunset active development and maintain the asset as a low-touch legacy utility. **Best for:** Software developers and computer science students requiring offline access to standard design pattern definitions. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset active development because the 19-month update gap signals a low-priority legacy asset → reduce maintenance overhead ### Outlook: Declining The market for static pattern references is consolidating around free, browser-accessible documentation that offers search and code-copying capabilities. Design Pattern Reference remains in maintenance mode, which will likely lead to further decline in relevance as developer workflows shift toward integrated, living documentation. - 🔴 The 19-month update gap indicates a lack of active feature investment, which erodes the value proposition against free, updated web resources. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 1 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Design Pattern Reference** (this app) | N/A/5 | N/A | 强 马 | | [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:** 强 马 - **Website:** [https://itunes.apple.com/us/app/id946885365?mt=8](https://itunes.apple.com/us/app/id946885365?mt=8) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/design-pattern-reference/id946885365?uo=4) - **Dev Site:** [Official Website](https://itunes.apple.com/us/app/id946885365?mt=8) - **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.
