It holds a 2/5 rating from 4 reviews. > **Bottom Line:** Vocabulary・English Flash Cards is a dormant asset that lacks the functional stability to compete in the education category, and the PM should sunset the current build to avoid further brand erosion. **Best for:** Students, test-takers, and language learners seeking to expand their English vocabulary for academic or professional advancement. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because the current build is non-functional and lacks a development roadmap → stop brand erosion ### Outlook: Declining The education flashcard market is consolidating around active, gamified platforms that provide daily engagement loops. Vocabulary・English Flash Cards remains exposed due to its static nature, and the lack of updates suggests it will continue to lose visibility until it is removed from the store. - 🔴 The 1,700-day update gap indicates a total lack of investment, which erodes user trust and prevents any possibility of market relevance. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 4 | | Sentiment | Upset (10/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Vocabulary・English Flash Cards** (this app) | 2/5 | Upset | Vocabulous US Inc. | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | n/a | 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:** Vocabulous US Inc. ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/vocabulary-english-flash-cards/id1591034814?uo=4) - **Sources:** 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・English Flash Cards still being updated?
