The lack of recent feature updates suggests a stable, maintenance-mode position rather than an aggressive growth strategy. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is offered as a free utility with no visible in-app purchase or subscription tiers, relying on its utility to attract users. ## SWOT Analysis {#swot} **Core Strengths:** - Simultaneous multi-source query mechanism reduces user search friction **Growth Levers:** - AI-driven vocabulary practice could increase session duration ## What's New - **Latest (v3.2.0, 6 months ago):** Removed Lexico and Macmillan dictionary support. ## App Momentum (Maintenance) {#momentum} - Removed Lexico and Macmillan dictionary support. - Six months since last store update. > **Cadence:** 1 total versions · 0 majors in last 6 months · 188 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} All English Dictionary is an education app that is completely free. It holds a 4.75/5 rating from 4 reviews. > **Bottom Line:** All English Dictionary provides a useful aggregation tool, but the lack of active development risks obsolescence against more dynamic reference apps. Maintaining the current search index quality is essential to retain the core user base until a new feature roadmap is established. **Best for:** Students and language learners preparing for standardized English proficiency exams like TOEFL, TOEIC, and GRE. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit search index performance because recent dictionary removals may have degraded result quality → maintain search utility ### Outlook: Stable The reference utility market is consolidating around apps that offer offline access and integrated study tools. All English Dictionary remains stable but exposed, as its reliance on external web sources makes it vulnerable to any changes in the availability of those dictionary APIs. - ⚪ The latest release focused on removing dictionary content, indicating a maintenance-only posture rather than active feature expansion. - ⚪ Six months of inactivity suggests the app is currently in a steady state, serving a niche audience without aggressive growth targets. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.75/5 | | Total Reviews | 4 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **All English Dictionary** (this app) | 4.75/5 | N/A | ILHWAN CHO | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** ILHWAN CHO - **Website:** [https://www.oolac.com](https://www.oolac.com) ## Data Sources & Links - **App Store ID:** 433593751 - **Dev Site:** [Official Website](https://www.oolac.com) - **Sources:** App store metadata. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is All English Dictionary free to use?
