**[CalcFinals](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals)** by Russel Glass: While more academic, it occupies the same education category by providing tools for grade and class management. - Focuses on utility-driven class management rather than the gamified mental calculation drills found in AnzanDojo. - Provides scenario analysis tools that help students project their final grades based on current performance. - **[Geometric Calculator X](https://marlvel.ai/apps/geometric-calculator-x)** by Yoshiaki Onishi: It serves the same educational market by providing automated calculation tools for specific mathematical domains. - Automates complex geometric computations, shifting the focus from mental arithmetic to formula-based problem solving. - Includes a comprehensive formula reference library, acting as a study aid rather than a training game. - **[Linear Algebra Pro](https://marlvel.ai/apps/linear-algebra-pro)** by ALG Software Lab: It competes for the same student user base by offering specialized calculators and practice generators for advanced math. - Provides step-by-step calculator breakdowns that teach the methodology behind the math rather than just the result. - Supports multi-language functionality, significantly expanding its potential reach compared to this app's current localization. - **[Fractions Calculator](https://marlvel.ai/apps/fractions-calculator-2)** by Corporate Smalltalk Consulting Ltd: This app addresses the same fundamental arithmetic needs as AnzanDojo but focuses on fraction-specific operations. - Includes a paper tape history feature, allowing users to review their previous calculations for error checking. - Specializes in mixed fraction and decimal arithmetic, providing a deeper toolset for specific curriculum requirements. ### New Kids on the Block (What's Innovative) - **[Easy Spoken English](https://marlvel.ai/apps/com-easyspokenenglish-app)** by MAFTEAN CONSTRUCTION LTD: Though language-focused, it uses similar gamified arithmetic challenges and immediate failure states to drive engagement. - Implements an immediate failure state mechanic that creates high-stakes pressure during quick-fire learning sessions. - **[Geometry Calculator PRO-YOKIE](https://marlvel.ai/apps/geometry-calculator-pro-yokie)** by nakhon phagdeechat: A new entrant in the education space that provides specialized calculation tools with a focus on UI customization. - Offers extensive UI customization and offline functionality, prioritizing user comfort and accessibility over gamified drills. ## What's New - **Latest (v1.6.2, 7 years ago):** Fixed layout issue occurring during screen rotation. ## App Momentum (Zombie) {#momentum} - Dormant development for over 89 months. - No feature releases since 2018. > **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 education app that is completely free. > **Bottom Line:** AnzanDojo's lack of updates for over seven years signals a sunset posture, as the app has been superseded by rivals offering structured progression and social features. **Best for:** Elementary school pupils and adults seeking mental math exercises to replace calculator dependency. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because it has remained in maintenance mode since 2018 → reallocate resources to higher-yield projects. ### Feature Gaps vs Competitors - Social leaderboards (available in Math Hit but absent here) ### Outlook: Declining The education category is consolidating around apps that offer high-frequency content updates and social gamification. AnzanDojo's stagnant state leaves it exposed to churn, as users naturally migrate to competitors that provide fresh challenges and social proof. - 🔴 The seven-year development hiatus indicates the app is in maintenance mode, which accelerates user migration to actively supported rivals. ## 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. | | [Easy Spoken English](https://marlvel.ai/apps/com-easyspokenenglish-app) | N/A/5 | N/A | MAFTEAN CONSTRUCTION LTD | | [Math Hit: Math Games for Brain](https://marlvel.ai/apps/com-sydistinctartsgames-tryout) | 4.6/5 | N/A | ABYLITH GAMES LLP | | [CalcFinals](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals) | 5.0/5 | N/A | Russel Glass | | [Mental Math Pro - Math Quiz](https://marlvel.ai/apps/mental-math-pro-math-quiz) | 4.2/5 | N/A | Peikun Duan | | [Linear Algebra Pro](https://marlvel.ai/apps/linear-algebra-pro) | 5.0/5 | N/A | ALG Software Lab | ## 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 - [*Easy Spoken English*](https://marlvel.ai/apps/com-easyspokenenglish-app) (MAFTEAN CONSTRUCTION LTD) · N/A Rating - [*Math Hit: Math Games for Brain*](https://marlvel.ai/apps/com-sydistinctartsgames-tryout) (ABYLITH GAMES LLP) · 4.6/5 Rating - [*CalcFinals*](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals) (Russel Glass) · 5.0/5 Rating - [*Mental Math Pro - Math Quiz*](https://marlvel.ai/apps/mental-math-pro-math-quiz) (Peikun Duan) · 4.2/5 Rating - [*Linear Algebra Pro*](https://marlvel.ai/apps/linear-algebra-pro) (ALG Software Lab) · 5.0/5 Rating - [*Fun Math - Mental speed training game*](https://marlvel.ai/apps/fun-math-mental-speed-training-game) (Batuhan Bayar) · 4.1/5 Rating - [*Geometry Calculator PRO-YOKIE*](https://marlvel.ai/apps/geometry-calculator-pro-yokie) (nakhon phagdeechat) · N/A Rating - [*Geometric Calculator X*](https://marlvel.ai/apps/geometric-calculator-x) (Yoshiaki Onishi) · 2.0/5 Rating - [*Operation Math Game*](https://marlvel.ai/apps/operation-math-game) (Little 10 Robot) · 4.5/5 Rating - [*Fractions Calculator*](https://marlvel.ai/apps/fractions-calculator-2) (Corporate Smalltalk Consulting Ltd) · 4.5/5 Rating ## Frequently Asked Questions {#faq} ### Is AnzanDojo still being updated?
