Static content, no recent feature updates. > **Cadence:** 2 total versions · 0 majors in last 6 months · 2319 days since last update · 619 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} 英検®2級予想問題ドリル is an established education app that is a paid app. > **Bottom Line:** The app maintains a strong content foundation through Obunsha's curriculum, but its static delivery model is losing ground to adaptive, AI-assisted competitors, so the PM must prioritize engagement features like notifications to defend the user base. **Best for:** Students and individuals preparing for the Eiken Grade 2 examination who prefer self-study via mobile devices. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship automated study notifications because competitors use them to drive daily active usage → increase retention. — *Competitors like NCLEX PN & RN Medic Test 2026 use notifications to maintain daily engagement, which is missing here.* _(trade-off: deprioritize Pause the UI refresh of the strategy guide — notification logic has a higher impact on daily retention.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Add performance tracking dashboard because users need to visualize progress → reduce churn to adaptive competitors. — *Competitors offer granular performance statistics, a feature currently missing that prevents users from tracking their exam readiness.* _(trade-off: deprioritize Deprioritize the addition of new question banks — current volume is sufficient for the exam scope.)_ ### Feature Gaps vs Competitors - AI-driven personalized feedback (available in CDL Practice Test 2026) - Automated study notifications (available in NCLEX PN & RN Medic Test 2026) - Multi-modal audio lessons (available in Canadian Citizenship 2026) ### Outlook: Stable The test-prep market is shifting toward adaptive, AI-assisted learning tools that gamify progress and provide real-time feedback. This app remains stable due to its trusted content, but it faces long-term churn risk as students migrate to platforms that offer more interactive study experiences. - 🔴 The lack of feature updates since the initial release leaves the app vulnerable to competitors with modern, adaptive learning interfaces. - ⚪ The paid-upfront model remains a stable revenue stream for users who prefer avoiding subscriptions, though it limits the app's growth potential. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Paid | | Platforms | iOS & Android | | Key Features | 4 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **英検®2級予想問題ドリル** (this app) | N/A/5 | N/A | StudySwitch, Inc. | | [CDL Practice Test 2026 by ABC](https://marlvel.ai/apps/cdl-practice-test-2026-by-abc) | 4.9/5 | Thrilled | Thanh Hung | | [ATI TEAS Practice Test](https://marlvel.ai/apps/ati-teas-practice-test) | N/A/5 | N/A | Draunt LLC | | [NCLEX PN & RN Medic Test 2026](https://marlvel.ai/apps/nclex-pn-rn-medic-test-2026) | 4.7/5 | N/A | Apps Labs | | [Canadian Citizenship 2026](https://marlvel.ai/apps/canadian-citizenship-2026-1) | 4.6/5 | N/A | Apps Labs | | [EduTest](https://marlvel.ai/apps/edutest) | N/A/5 | N/A | RB Tech Services | ## 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-2%E7%B4%9A%E4%BA%88%E6%83%B3%E5%95%8F%E9%A1%8C%E3%83%89%E3%83%AA%E3%83%AB/id1368900404?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=jp.co.studyswitch.drilleikeng2&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. ## Related Intel Reports - [*CDL Practice Test 2026 by ABC*](https://marlvel.ai/apps/cdl-practice-test-2026-by-abc) (Thanh Hung) — 4.9/5 Rating | Excellent Sentiment - [*ATI TEAS Practice Test*](https://marlvel.ai/apps/ati-teas-practice-test) (Draunt LLC) — N/A Rating | N/A Sentiment - [*NCLEX PN & RN Medic Test 2026*](https://marlvel.ai/apps/nclex-pn-rn-medic-test-2026) (Apps Labs) — 4.7/5 Rating | N/A Sentiment - [*Canadian Citizenship 2026*](https://marlvel.ai/apps/canadian-citizenship-2026-1) (Apps Labs) — 4.6/5 Rating | N/A Sentiment - [*EduTest*](https://marlvel.ai/apps/edutest) (RB Tech Services) — N/A Rating | N/A Sentiment - [*MFT Exam Lite*](https://marlvel.ai/apps/mft-exam-lite) (LICENSURE EXAMS INC) — 1.6/5 Rating | Negative Sentiment - [*YKS*](https://marlvel.ai/apps/yks) (Mehmet Bayram) — 5.0/5 Rating | N/A Sentiment - [*USA Naturalization Test Prep*](https://marlvel.ai/apps/usa-naturalization-test-prep) (Nhu Nguyen) — 5.0/5 Rating | N/A Sentiment - [*Civics Flash*](https://marlvel.ai/apps/civics-flash) (Richard Stokes) — 5.0/5 Rating | N/A Sentiment - [*Secure Exam*](https://marlvel.ai/apps/secure-exam) (Emcan) — 5.0/5 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.
