US Market. No publisher influence. > **Key Insight:** AnzanDojo is a education app by ZOOMO Inc.. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Education | | **Developer** | ZOOMO Inc. | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 0d | ## Metadata & Market Performance - **Publisher:** ZOOMO Inc. - **Category:** Education - **Target Audience:** Elementary school pupils and adults seeking mental math exercises to replace calculator dependency. - **Platforms:** iOS - **Version Audited:** 1.6.2 - **Audit Date:** 2026-05-12 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 490112421 - **Bundle ID:** jp.zoomo.AnzanDojo - **Performance Trend:** Declining - **Data Window:** Analysis based on signals collected up to 2026-05-12 ## Executive Snapshot **What it is:** AnzanDojo is a mental math drill app for elementary students and adults, structured around timed calculation challenges. **Why users hire it:** Users hire the app to replace calculator dependency with mental exercises, but the lack of progress tracking forces users to manually record their own improvement. ## App DNA (Features & Intent) - **[Standard] Mental Calculation Challenges:** Timed math drills requiring 10 consecutive correct answers - **[Standard] Difficulty Levels:** Three distinct tiers adjusting math complexity - **[Differentiator] Twitter Score Sharing:** Manual posting of high scores to Twitter ## Market Position {#market-position} AnzanDojo occupies the free utility segment of the Education category, but its lack of updates since 2018 prevents it from competing with modern, adaptive learning tools. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no visible in-app purchase or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Distraction-free mental math drill loop sustains focus - Pass-system buffer prevents early-session churn **Critical Frictions:** - No updates since 2018 - Manual Twitter sharing is high-friction - Lacks progress tracking **Growth Levers:** - Integrate automated progress visualization - Add modern social leaderboards **Market Threats:** - Competitors with adaptive difficulty - Lack of maintenance risks store delisting ## Recent Changes (v2 → v3) {#recent-changes} The app's status has shifted from a neglected utility to a sunset project, with the competitive landscape updated to reflect current market alternatives. **Overall trend**: Declining **Compared at**: 2026-05-12 ### High-impact changes - **[Shifted] Sunset Decision** (positioning) — PM action item changed from 'Invest' in performance tracking to 'Sunset' the app due to the 6-year update gap. - **[Shifted] Competitive Landscape Overhaul** (positioning) — Removed all previous nemeses and contenders, replacing them with a new list of active competitors including Math Facts and Multiplication Math Facts. ### Medium-impact changes - **[Added] Updated SWOT Risks** (swot) — Added 'Lack of maintenance risks store delisting' as a threat and 'Manual Twitter sharing is high-friction' as a weakness. ## What's New - **Latest (v1.6.2, 7 years ago):** Fixed layout issue occurring during screen rotation. ## App Momentum (Zombie) {#momentum} - Last major update released 2018. - No new features added recently. > **Cadence:** 1 total versions · 0 majors in last 6 months · 2760 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} AnzanDojo is an established education app that is completely free. > **Bottom Line:** AnzanDojo provides a functional mental math utility, but its total lack of development since 2018 makes it a sunset asset, so the developer should pivot to a modern, adaptive math-learning framework to remain relevant. **Best for:** Elementary school pupils and adults seeking mental math exercises to replace calculator dependency. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] [MEDIUM IMPACT] Sunset the app because the 2018 last-update date signals abandonment → focus resources on new projects. — *The app has not received an update in over 6 years, indicating it is no longer a priority.* _(trade-off: deprioritize No engineering capacity displaced as the app is already in maintenance mode.)_ ### Feature Gaps vs Competitors - Adaptive difficulty levels (available in Math Facts) - Teacher-access accounts (available in Login Access: DB Algebra 12+) - Automated progress tracking (available in Multiplication Math Facts) ### Outlook: Declining The educational app market is shifting toward adaptive, data-driven learning experiences that provide tangible progress metrics. AnzanDojo's static, unmaintained state leaves it exposed to competitors that offer personalized feedback, so the app will likely continue to lose relevance. - 🔴 The lack of updates since 2018 indicates the app is in maintenance mode, which prevents it from competing with modern, adaptive learning tools. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **AnzanDojo** (this app) | N/A/5 | N/A | ZOOMO Inc. | | [Odd Squad: Odd-mented Reality](https://marlvel.ai/intel-report/education/odd-squad-odd-mented-reality) | 2.4/5 | Frustrated | Sinking Ship Interactive Inc. | | [Login Access: DB Algebra 12+](https://marlvel.ai/intel-report/education/login-access-db-algebra-12) | 2.1/5 | Upset | Kahoot DragonBox AS | | [Fractions Calculator](https://marlvel.ai/intel-report/education/fractions-calculator-2) | 4.5/5 | N/A | Corporate Smalltalk Consulting Ltd | | [Long Addition and Subtraction](https://marlvel.ai/intel-report/education/long-addition-and-subtraction) | N/A/5 | N/A | OCD Inc. | | [Multiplication Math Facts](https://marlvel.ai/intel-report/education/multiplication-math-facts) | N/A/5 | N/A | OCD Inc. | ## Company Profile - **Developer:** ZOOMO Inc. ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/anzandojo/id490112421?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Odd Squad: Odd-mented Reality*](https://marlvel.ai/intel-report/education/odd-squad-odd-mented-reality) (Sinking Ship Interactive Inc.) — 2.4/5 Rating | Negative Sentiment - [*Login Access: DB Algebra 12+*](https://marlvel.ai/intel-report/education/login-access-db-algebra-12) (Kahoot DragonBox AS) — 2.1/5 Rating | Terrible Sentiment - [*Fractions Calculator*](https://marlvel.ai/intel-report/education/fractions-calculator-2) (Corporate Smalltalk Consulting Ltd) — 4.5/5 Rating | N/A Sentiment - [*Long Addition and Subtraction*](https://marlvel.ai/intel-report/education/long-addition-and-subtraction) (OCD Inc.) — N/A Rating | N/A Sentiment - [*Multiplication Math Facts*](https://marlvel.ai/intel-report/education/multiplication-math-facts) (OCD Inc.) — N/A Rating | N/A Sentiment - [*Math Facts*](https://marlvel.ai/intel-report/education/math-facts) (OCD Inc.) — 3.9/5 Rating | Mixed Sentiment - [*Flashcards Deluxe*](https://marlvel.ai/intel-report/education/flashcards-deluxe) (OrangeOrApple.com) — 4.5/5 Rating | Excellent Sentiment - [*AlgoApp - Flashcards*](https://marlvel.ai/intel-report/education/algoapp-flashcards) (AlgoApp Inc) — 4.6/5 Rating | Negative Sentiment - [*Flashcards maker - AI generate*](https://marlvel.ai/intel-report/education/flashcards-maker-ai-generate) (Teleprompter LLC) — 4.1/5 Rating | Mixed Sentiment - [*Elevate - Brain Training Games*](https://marlvel.ai/intel-report/education/elevate-brain-training-games) (The Mind Company) — 4.7/5 Rating | Mixed 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.
