Rubik: learn the method
A planned AI tutor that explains why a cube move works, breaks algorithms into manageable steps, and adapts explanations to the learner’s experience.
About EzApp
Rooted in indie development. Building toward more helpful apps.
EzApp is a small, founder-led mobile product studio that grew out of independent app development. Its portfolio spans board games, cube puzzles, solitaire, and music practice on iOS and Android. The studio’s direction is to build AI-enabled applications that help people learn by doing, starting with guidance inside products already available to players.
The studio behind the apps
EzApp is the studio’s website brand at ezapp.dev. Existing app listings may use the publisher name EzHub. The product links below connect this website to those listings. Founded and run by an indie developer, the studio keeps product development and support close to the people using its apps.

support@ezapp.devOur direction: learning inside the experience
When someone gets stuck in a puzzle or game, a useful explanation should be available right where the question arises. Our vision is to make everyday apps more responsive to what people are trying to learn: explain a difficult step, answer a follow-up question, and help them make the next decision with greater confidence.
We plan to start with focused learning features in the existing portfolio, evaluate whether they help players understand and progress, and use those lessons to shape future AI-enabled apps. Clear explanations, reliable guidance, and simple mobile experiences will guide that work.
How Claude fits into the work
Claude supports the studio’s research into AI features for existing and future products. The focus is practical: help a player understand a cube algorithm, reason through a card-game decision, or learn from a Gomoku position. The planned API integrations would bring those explanations into the apps, grounded in each game’s rules and available engine analysis.
The existing portfolio
From an on-device Gomoku opponent to step-by-step cube solutions and playable musical instruments, each app focuses on a specific experience. Follow the store links for release information and availability.

What comes next · AI roadmap
From showing the next move to explaining why it matters.
Our next focus is AI-assisted learning: helpful explanations based on what you are doing inside an app. Starting with our existing games, we plan to make it easier to ask questions, understand your choices, and build skills as you play.
Solitaire: understand the next move
Planned contextual guidance that explains legal moves, compares possible choices, and helps players understand a strategy instead of following a hint blindly.
Gomoku: see the strategy
A planned coach that turns board positions and engine analysis into approachable explanations of threats, defensive moves, and missed opportunities.
A useful coach should understand the position in front of you and explain it at your level. Our research explores Claude alongside game rules and engine analysis, with a focus on accurate explanations and guidance that beginners can put into practice.
These features are planned and are not included in the current releases. The goal is optional online coaching alongside the existing gameplay. Availability, connectivity requirements, and data handling will be documented before any AI feature launches.
