AnzanDojo
For elementary school pupils and adults seeking mental math exercises to replace calculator dependency.
AnzanDojo is an established education app that is completely free.
What is AnzanDojo?
AnzanDojo is a mental math drill app for elementary students and adults, structured around timed calculation challenges.
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.

How's The Education Market?
AnzanDojo operates as a free utility in the Education category, lacking in-app purchases or subscription gates. Its positioning relies on a simple, distraction-free math drill format rather than the sophisticated progression systems found in modern educational titles.
The rivals identified
Nemeses(1)
Math Hit directly competes for the same elementary-aged audience by gamifying arithmetic through high-frequency cognitive challenges and social leaderboards.
Contenders(4)
It targets the same elementary demographic but uses a mission-based narrative to make math practice more immersive.
This app competes by offering a quiz-based format that mirrors the target's goal of improving mental math proficiency.
It overlaps with AnzanDojo by offering a dedicated mental speed training mode designed to improve calculation reflexes.
This app targets the same educational niche by focusing on multiplication mastery through randomized testing and custom difficulty settings.
Same space(3)
This app addresses the same fundamental arithmetic needs as AnzanDojo but focuses on fraction-specific operations.
Differentiators
- Offers paper tape history functionality which provides a tangible audit trail for complex fraction calculations.
- Utilizes gesture-based editing to streamline the input process for students working on multi-step arithmetic problems.
It competes for the same student user base by offering specialized calculators and practice generators for advanced math.
It serves the same educational market by providing automated calculation tools for specific mathematical domains.

The outtake for AnzanDojo
Strengths to defend, gaps to attack
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
What are the next best moves?
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: No engineering capacity displaced as the app is already in maintenance mode.
A counter-intuitive read
The app's lack of updates is not just a failure of maintenance, but a strategic signal that the developer has abandoned the consumer-utility model for this specific niche.
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)
Key Takeaways
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.
Where Is It Heading?
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.
