Understanding the problem

Understanding the starting point


When I first encountered Calculia, it was clear that the tool, while valuable in diagnosing dyscalculia, was being held back by several usability and functional limitations. To address these issues, I started with a comprehensive analysis to identify the most pressing pain points and understand how the application could better serve its users.


Exploring the current version


Through my analysis of the tool, I pinpointed several critical problems that needed to be addressed. I had full access to the existing software and its user manual, which allowed me to thoroughly test the program and understand how it functioned.







Challenges


During my analysis, I identified several issues that made Calculia harder to use and less effective





Gathering feedback


While I didn't have direct access to user feedback, the team involved in the project had a strong connection with therapists and educators who used the tool. I relied on their insights and learned that Calculia ( previous "ProKalkulia 6-9") was already used by over 100 institutions in Poland, but the outdated interface and lack of automation posed significant challenges.



Setting up an organizational space


I created a @Notion workspace to document all insights, structure team meetings, and keep track of progress. This provided a clear space for collaboration and alignment on priorities.





Kickoff insights


During the kickoff phase, we aligned on key project goals, identified risks, and established a clear roadmap. Below is a summary of the structured planning process we followed to ensure smooth progress and clarity across the team.





Creating a budget plan


To ensure the success of Calculia’s redesign, I developed a structured budget plan that prioritized resource allocation across key areas: design, development, and research. This plan not only optimized costs but also ensured the team could meet critical project milestones effectively.

Documentation and collaboration


Using Notion, I organized research findings, created a centralized space for team collaboration, and aligned project goals with user needs and business objectives.


Ideation

Brainstorming

I began the ideation phase with a free-form brainstorming session, encouraging the team to think creatively and propose any ideas that could enhance the tool. This approach helped us uncover a wide range of possibilities, from core functionality improvements to innovative solutions for usability challenges





To make sense of the collected ideas, I structured them into functional categories, such as navigation, user interaction, and subscription process. This step allowed us to identify key areas for improvement without overcomplicating the process




We prioritized features based on their impact and feasibility, focusing on solving the tool’s biggest usability problems. This included simplifying workflows, improving data clarity, and implementing customizable features for different user needs.




This process provided a clear direction for the next phase, with actionable ideas for prototyping and a strong foundation for user-centered improvements

Prototyping

Path the usability

Building on the insights gathered during research and brainstorming, I outlined the user flow and defined key functionalities to address the tool’s main challenges. Collaboration with a graphic designer ensured the final design was both intuitive and visually appealing, balancing professionalism with child-friendly elements.

This streamlined approach focused on usability and efficiency, delivering a design ready for implementation without unnecessary complexity.


Flowcharts

I highlighted two flowcharts that have significantly changed in the new version of the app.

Streamlined registration and purchase flow

The new workflow automates the process of license delivery, removing manual steps. Users now receive immediate access after completing registration and payment, enhancing both usability and efficiency.






Simplified test data input process

By reducing unnecessary steps and focusing on essential data, the revamped workflow ensures a smoother experience for users while maintaining accuracy in test records.





Iterative process: Two major prototyping rounds


The prototyping phase consisted of at least two key iterations:


💬 Initial feedback

• After sketching the wireframes, I reviewed them with team to confirm that the structure and flow aligned with their expectations.

• Small adjustments were made based on feedback, particularly around the sequencing of steps in the testing process.


🎨 Visual refinement

• After locking the functionality and flow, I collaborated with a ui designer to establish the visual style of the tool.

• We discussed color palettes and overall aesthetics to ensure the interface was clean, professional, yet approachable for an educational context.

• Once the visuals were approved, I moved on to high-fidelity prototypes in Figma to finalize the design.



Design Principles: clean and user-centric


My key design goals included:

Clarity and simplicity: Since this tool is used by both children and therapists, the interface had to be intuitive and distraction-free.

Educational aesthetics: The design needed to balance a professional look with subtle educational and playful elements that would make it approachable for children.

Consistency: Ensuring all elements followed a cohesive visual language to create a seamless experience.


Challenges and adaptations


While most design decisions were straightforward, the biggest challenge was defining a visual tone that balanced professionalism for therapists with an engaging experience for children. Through iterative prototyping, I explored different visual approaches and collaborated with the ui designer to refine the concept.


Since the focus was on prototyping and refining functionality, rather than building a full design system, we prioritized clear layouts and user-friendly interactions. The final design aimed to be intuitive, accessible, and aligned with the tool’s educational purpose.

What we achieved


The redesign of Calculia addressed its most critical limitations: outdated visuals, an inefficient subscription model, and a lack of automation. By creating a cleaner, modernized interface and defining a scalable business model, we’ve transformed a niche educational tool into a product with the potential to scale internationally.


Key achievements include


• Transitioning from a lifetime subscription model to a scalable solution, paving the way for SaaS implementation.


• Simplifying the user flow for both therapists and children to reduce cognitive load during testing.


• Laying the groundwork for improved marketability and accessibility.
