1181-question database provides high-volume test prep utility **Critical Frictions:** - Ad-only monetization model limits capital for feature iteration - Lack of offline mode restricts usage in transit - No social engagement mechanics to drive retention **Growth Levers:** - Introduce a premium, ad-free subscription tier to capture power users - Implement offline-first study modes to increase daily active usage **Market Threats:** - Gamified rivals like Learn Arabic siphon daily active users via social leaderboards - High-stakes proctored exam apps threaten the relevance of simple drill-based tools ## Recent Changes (v3 → v4) {#recent-changes} The app's competitive position is under pressure due to newly identified user complaints regarding ad-delivery and offline access, prompting a shift in PM priorities toward offline-first utility. **Overall trend**: Mixed **Compared at**: 2026-05-24 ### High-impact changes -

Supported GIGA School iPad distribution. > **Cadence:** 5 total versions · 2 majors in last 6 months · 71 days since last update · 190 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} 英検®問題集 is a market-leading education app that is completely free. With a 4.64/5 rating from 64 reviews, it delivers strong user satisfaction. > **Bottom Line:** The app holds a strong niche in Eiken test prep through its free question database, but the lack of offline access and social engagement leaves it exposed to gamified rivals, so the PM should prioritize offline functionality to stabilize daily usage. **Best for:** Students preparing for Eiken English proficiency exams (Grades 2, Pre-2, and 3) and schools participating in the GIGA School program. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship offline study mode because user reviews flag transit-study friction → increase daily active usage — *Offline-mode is the top-cited frustration in sentiment analysis.* _(trade-off: deprioritize Pause the writing auto-grading update — offline utility has 3× the impact on daily retention.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Implement weekly leaderboards because gamified rivals siphon users via social competition → improve retention — *Competitor analysis shows gamified ranking is the primary hook for language-learning apps.* _(trade-off: deprioritize Same-quarter capacity available — no major lever displaced.)_ ### Feature Gaps vs Competitors - Offline course access (available in Learn Arabic but missing here) - Weekly ranking system (available in Learn Arabic but missing here) - Native audio with speed control (available in Learn Arabic but missing here) ### Outlook: Stable The Eiken test prep market is consolidating around apps that offer both high-volume drills and social engagement, leaving the target app's drill-only model exposed. Without a shift toward offline-first utility or social features, the app will likely see stagnant growth as users migrate to more interactive, gamified alternatives. - 🔴 Ad-network interruptions in the latest version erode study flow, which compounds the churn pressure from gamified language rivals. - ⚪ Recent updates focused on stability, no feature expansion, signaling a maintenance-mode posture that leaves the app vulnerable to competitor innovation. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.64/5 | | Total Reviews | 64 | | Sentiment | Excited (80/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 4 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **英検®問題集** (this app) | 4.64/5 | Excited | StudySwitch, Inc. | | [Esperanto-English Dictionary](https://marlvel.ai/intel-report/reference/esperanto-english-dictionary) | 3.5/5 | N/A | FB PUBLISHING LLC | | [CRNA School Prep Academy](https://marlvel.ai/intel-report/education/crna-school-prep-academy) | 5.0/5 | N/A | CRNA School Prep Academy Inc. | | [Kana Town](https://marlvel.ai/intel-report/education/kana-town) | 4.7/5 | N/A | Guillaume Bernard | | [imiwa?](https://marlvel.ai/intel-report/reference/imiwa) | 4.8/5 | Excited | Pierre-Phi di Costanzo | | [Learn Persian (Beginners)](https://marlvel.ai/intel-report/education/learn-persian-beginners) | 4.5/5 | N/A | BNR LANGUAGES INC. | ## Company Profile - **Developer:** StudySwitch, Inc. - **Website:** [https://www.studyswitch.co.jp/?appstore](https://www.studyswitch.co.jp/?appstore) - **Social:** [Facebook](https://www.facebook.com/391154754640977?ref=embed_page) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/%E8%8B%B1%E6%A4%9C-%E5%95%8F%E9%A1%8C%E9%9B%86/id1045845439?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=jp.co.gakkonet.quizshootereiken2&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.studyswitch.co.jp/?appstore) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Esperanto-English Dictionary*](https://marlvel.ai/intel-report/reference/esperanto-english-dictionary) (FB PUBLISHING LLC) — 3.5/5 Rating | N/A Sentiment - [*CRNA School Prep Academy*](https://marlvel.ai/intel-report/education/crna-school-prep-academy) (CRNA School Prep Academy Inc.) — 5.0/5 Rating | N/A Sentiment - [*Kana Town*](https://marlvel.ai/intel-report/education/kana-town) (Guillaume Bernard) — 4.7/5 Rating | N/A Sentiment - [*imiwa?*](https://marlvel.ai/intel-report/reference/imiwa) (Pierre-Phi di Costanzo) — 4.8/5 Rating | Positive Sentiment - [*Learn Persian (Beginners)*](https://marlvel.ai/intel-report/education/learn-persian-beginners) (BNR LANGUAGES INC.) — 4.5/5 Rating | N/A Sentiment - [*Learn Hindi (Beginners)*](https://marlvel.ai/intel-report/education/learn-hindi-beginners) (BNR LANGUAGES INC.) — 4.8/5 Rating | Positive Sentiment - [*Learn Arabic (Beginners)*](https://marlvel.ai/intel-report/education/learn-arabic-beginners) (BNR LANGUAGES INC.) — 4.6/5 Rating | Positive Sentiment - [*Learn Catalan (Beginners)*](https://marlvel.ai/intel-report/education/learn-catalan-beginners) (BNR LANGUAGES INC.) — 5.0/5 Rating | N/A Sentiment - [*Secure Exam*](https://marlvel.ai/intel-report/education/secure-exam) (Emcan) — 5.0/5 Rating | N/A Sentiment - [*EF Campus Connect*](https://marlvel.ai/intel-report/education/com-ef-campusconnect) (Signum International AG) — 4.0/5 Rating | N/A Sentiment ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** — Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** — Identifies the app's core features, monetization model, target audience, and competitive positioning.
