It holds a 4.67/5 rating from 257 reviews. > **Bottom Line:** The lack of development since 2019 leaves English Idioms in Use vulnerable to technical decay, and the reported launch failures suggest the app no longer functions for a portion of the user base. Prioritizing a stability patch would address the primary churn driver. **Best for:** English language learners seeking to improve their knowledge of idioms, phrasal verbs, and American slang. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit launch sequence because persistent launch failures are the top-reported complaint → restore core accessibility ### Outlook: Declining The language-learning market is consolidating around platforms with active, multi-week release cadences, leaving static reference tools like English Idioms in Use increasingly exposed. Without a stability patch to address the reported launch failures, the app will continue to lose its remaining user base to more reliable alternatives. - 🔴 Persistent launch failures in the latest version erode the daily active habit, which compounds the rating drag already visible on the App Store. - 🔴 The seven-year development gap signals that English Idioms in Use is in maintenance mode, leaving it exposed to modern, actively updated competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.67/5 | | Total Reviews | 257 | | Sentiment | Frustrated (35/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **English idioms in use** (this app) | 4.67/5 | Frustrated | Nguyen Thi Thanh Huyen | | [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:** Nguyen Thi Thanh Huyen ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/english-idioms-in-use/id1463792529?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 English Idioms in Use suitable for beginners?
