This shift from a free utility to a paid, high-pressure certification model has created significant reputational risk. **Overall trend**: Declining **Compared at**: 2026-07-30 ### High-impact changes - **[Shifted] Pricing Model Reclassification** (pricing) - **[Declined] Emergence of Critical Technical Complaints** (sentiment) ### Medium-impact changes - **[Added] Strategic SWOT Update** (swot) ## Rivals Landscape {#rivals} > Competitive positioning identified by AI analysis of app features, category, and market signals. ### DET - Duolingo English Test vs IELTS Prep App: Take IELTS - Top Rival - **IELTS Prep App: Take IELTS** by British Council: Direct competitor in the high-stakes English proficiency certification market with a focus on remote/digital testing preparation. - **TOEFL Go! Official Prep** by Educational Testing Service: The official mobile companion for the TOEFL exam, competing directly for the same academic and professional certification user base. ### Contenders (Strong Challengers) - **IELTS Prep - British Council** by British Council: Provides comprehensive preparation tools and booking features for the world's leading English language test. - **Cambridge English Exam Prep** by Cambridge University Press & Assessment: Offers official preparation materials for Cambridge English exams, targeting the same demographic of international students and professionals. ### Peers (What They Do Better) - **ELSA: AI Learn & Speak English** by ELSA Corp: Focuses on English proficiency improvement, often used as a precursor to taking formal certification tests. - **Magoosh English Lessons** by Magoosh: Provides test prep content for English proficiency exams, capturing users in the study phase before they register for a test. - **British Council EnglishScore** by British Council: Offers a mobile-based English proficiency test that provides a certificate, serving as a direct alternative for quick, remote assessment. - **Quizlet: AI-powered Flashcards** by Quizlet Inc.: Widely used by students to memorize vocabulary and test patterns for standardized English exams. ### New Kids on the Block (What's Innovative) - **TestGlider - TOEFL Prep** by TestGlider: Uses AI-driven grading to provide instant feedback on practice tests, mimicking the speed and efficiency of the Duolingo English Test. - **PrepAdviser** by PrepAdviser: Emerging platform focusing on streamlining the path to international education, including test preparation and institutional requirements. ## What's New - **Latest (v1.2.5, 8 months ago):** Maintenance update focused on bug fixes and performance improvements. ## App Momentum (Maintenance) {#momentum} - Ships minor maintenance updates only. - Last major release eight months ago. > **Cadence:** 6 total versions · 0 majors in last 6 months · 183 days since last update · 12 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} DET - Duolingo English Test is an education app that is a paid app. It holds a 3.29/5 rating from 14 reviews. > **Bottom Line:** Technical instability during high-stakes exams invalidates the core value proposition of a secure, remote certification. Addressing the camera-malfunction errors is the only path to preventing a permanent shift of the user base toward traditional testing centers. **Best for:** Students and professionals requiring English proficiency certification for university admissions or institutional requirements. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit camera-driver compatibility because technical instability is the #1 churn driver → reduce forced-retake frequency ### Outlook: Declining The remote-proctoring market is consolidating around reliability, as institutions prioritize test integrity over cost. DET's maintenance-mode cadence leaves it exposed to rivals that can offer a more stable, error-free testing environment, which will likely accelerate churn toward traditional testing centers if stability is not addressed. - 🔴 Persistent technical instability during exams erodes the value of the certification, as users cannot rely on the platform for high-stakes outcomes. - 🔴 The 183-day release gap signals a shift to maintenance-only mode, leaving the platform vulnerable to competitors that offer more reliable remote-proctoring infrastructure. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.29/5 | | Total Reviews | 14 | | Sentiment | Upset (10/100) | | Confidence | Medium | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **DET - Duolingo English Test** (this app) | 3.29/5 | Upset | Duolingo | | [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:** Duolingo - **Website:** [https://englishtest.duolingo.com](https://englishtest.duolingo.com) - **Social:** [Instagram](https://www.instagram.com/duolingoenglishtest) · [Facebook](https://www.facebook.com/duolingoenglishtest) · [X/Twitter](https://twitter.com/duolingoentest) · [YouTube](https://www.youtube.com/watch) · [LinkedIn](https://www.linkedin.com/company/duolingo-english-test-) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/det-duolingo-english-test/id6754582936?uo=4) - **Dev Site:** [Official Website](https://englishtest.duolingo.com) - **Sources:** Developer website content, 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 the Duolingo English Test accepted by all universities?
