With a 4.66/5 rating from 2K reviews, it delivers strong user satisfaction. > **Bottom Line:** Maintaining the current offline-first utility will preserve the existing user base, but the lack of feature updates leaves the app vulnerable to rivals with active live-ops cadences. **Best for:** Individuals of all ages seeking to improve their vocabulary through gamified, self-paced learning. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship audio pronunciation support because missing audio is a top classroom complaint → increase utility for group instruction ### Outlook: Declining The educational app market is consolidating around platforms with frequent live-ops and social features. Vocabulary Builder: Vocab Word remains exposed due to its stalled development cadence and unresolved technical regressions, which will likely accelerate churn as users migrate to more responsive alternatives. - 🔴 The 307-day update gap indicates a shift to maintenance mode, which prevents the app from responding to emerging educational feature trends. - 🔴 Subscription-related billing complaints in reviews drive negative sentiment, which compounds the risk of platform-level enforcement actions. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.66/5 | | Total Reviews | 2K | | Sentiment | Excited (75/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Vocabulary builder: Vocab Word** (this app) | 4.66/5 | Excited | An Banh | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | Mixed | AlgoApp Inc | | [Elevate - Brain Training Games](https://marlvel.ai/apps/elevate-brain-training-games) | 4.7/5 | n/a | The Mind Company | | [Flashcards Deluxe](https://marlvel.ai/apps/flashcards-deluxe) | 4.5/5 | N/A | OrangeOrApple.com | | [Flash Cards Flashcards Maker](https://marlvel.ai/apps/flash-cards-flashcards-maker) | 4.0/5 | Mixed | Infinite Wave Media, LLC | | [Flashcards maker - AI generate](https://marlvel.ai/apps/flashcards-maker-ai-generate) | 4.1/5 | Mixed | Teleprompter LLC | ## Company Profile - **Developer:** An Banh - **Website:** [https://focus-thinh.web.app/](https://focus-thinh.web.app/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/vocabulary-builder-vocab-word/id1306464657?uo=4) - **Dev Site:** [Official Website](https://focus-thinh.web.app/) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating - [*Flash Cards Flashcards Maker*](https://marlvel.ai/apps/flash-cards-flashcards-maker) (Infinite Wave Media, LLC) · 4.0/5 Rating - [*Flashcards maker - AI generate*](https://marlvel.ai/apps/flashcards-maker-ai-generate) (Teleprompter LLC) · 4.1/5 Rating - [*Impulse - Brain Training*](https://marlvel.ai/apps/impulse-brain-training) (GMRD Apps Limited) · 4.6/5 Rating - [*Peak - Brain Training*](https://marlvel.ai/apps/peak-brain-training) (Synaptic Labs) · 4.7/5 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 ## Frequently Asked Questions {#faq} ### Is Vocabulary Builder: Vocab Word suitable for classroom use?
