Our role
End to end product development with responsibility for concept, design, implementation, and launch.
Idea
competenz4u is Austria's leading provider of exam preparation content tailored to the national education system.
To expand its business model, the company wanted to go beyond static website content and create a dedicated mobile learning experience. The goal was to meet students where they spend most of their time and enable daily exam preparation through a simple and motivating app.
Especially in Austria, where school attendance is not compulsory beyond a certain age, accessible learning support plays a critical role.
The app was designed to support students through structured practice, immediate feedback, and gamified elements that make learning more engaging and sustainable.
Solution
We designed and built a mobile learning platform that complements the existing content offering with interactive exam preparation.
The solution consists of a Flutter based mobile app, a back-end that manages learning logic and user progress, and an admin panel that gives competenz4u full control over content.
Core functionality was designed to work without mandatory registration, while optional accounts enable long term progress tracking and performance insights.
The system combines structured content hierarchies, intelligent question selection, and gamification into one scalable product.

Deployment
In a creative workshop, we analyzed the existing platform, defined goals for the mobile app, and translated requirements into a clear MVP roadmap focused on exam preparation use cases.
We developed a compact UI design system based on the existing brand while modernizing the look and feel for mobile usage. In parallel, the technical architecture for app and backend was prepared.
The mobile app and backend were developed across four structured sprints. Close collaboration allowed rapid feedback cycles and continuous alignment with competenz4u's expectations.
All features were tested individually and end to end. Bug fixes and refinements were applied to ensure stability and a smooth learning experience before launch.
The app was released and made available to users. We continue to support the platform to ensure long term stability and updates.

Main Features
User Registration and Profile Management
The app supports email based registration secured by a one time password verification process, as well as social logins via Apple, Google, and Facebook.
Registered users can manage personal data, review progress, and delete their account at any time.
Registration is optional and focused on long term learning continuity rather than access restriction, ensuring low entry barriers while enabling meaningful progress tracking over time.
Guest Access
Users can access core functionality without creating an account.
They can complete tests, earn points, appear on leaderboards, and review results as guests. At any point, users may convert their guest usage into a registered account, keeping all existing progress.
This approach lowers friction while preserving long term value.
Test Creation and Execution
Users select their learning path through a structured questionnaire covering school type, grade, subject, and topic.
An algorithm assembles quizzes from a categorized question pool, adapting difficulty based on previous success.
Correct answers are excluded over time, while incorrect questions reappear to reinforce learning.
Each test provides immediate feedback and scoring.
Performance Review and Statistics
All completed tests are available for review.
Users can analyze performance across subjects and topics, identify strengths and weaknesses, and track preparation progress.
This transparency supports more focused and effective exam preparation.
Leaderboard and Gamification
The app includes subject and topic specific rankings that allow students to compare their scores with peers across Austria.
Points and rankings introduce competition and motivation without distracting from learning objectives.
Main Challenge
The biggest challenge was designing a database and content structure that could represent complex school systems, topics, and subtopics while remaining flexible and reusable.
Topics needed to work across different school types and exams without duplication.
At the same time, competenz4u required a simple way to import and manage large volumes of questions created by teachers.
We addressed this through joint workshops, careful data modeling, and a CSV based import process that balanced structure with usability.
What We Learned
We learned that content heavy platforms require strong structural foundations from the beginning.
Early collaboration with domain experts and shared validation of data models prevents costly restructuring later.
Why This Matters for Our Partners
These learnings help partners build scalable content systems that can grow without losing clarity. They reduce operational overhead and enable independent content expansion.
Our Advice
If your product relies on complex content hierarchies, invest early in data modeling and editorial workflows. This ensures scalability without blocking non technical teams.
Most Special Step
The most special part of this project was the design of the intelligent test flow within the mobile app. Combining structured configuration, adaptive question selection, and gamification required close alignment between UX, learning logic, and back-end implementation.
The challenge was to make exam preparation feel motivating without trivializing the content.
By tailoring tests to user choices and past performance, the app supports meaningful learning while keeping students engaged and motivated to practice regularly.

RMN Events – Digitizing the USA’s #1 Kids Wrestling League
Adam Gutierrez
President, RMN Events LLC
RMN Events operates one of the largest children's wrestling leagues in the United States. Core processes such as event planning, athlete management, result tracking, and revenue handling relied on paper, spreadsheets, and disconnected tools. The idea was to digitize these processes end to end and create a single platform supporting athletes, coaches, spectators, and employees before, during, and after events.

Gesunde Zeiten - Simplifying Meal Planning for Families
Elsa Beerbaum
CEO & Founder, Gesunde Zeiten
Meal planning for families is often a demanding responsibility, especially for mothers who must balance allergies, dietary preferences, shared meals, leftovers, and limited time. What should support healthy living quickly becomes a daily source of stress. At the same time, balanced nutrition is essential for well-being and productivity, making this challenge impossible to ignore.Our partner's idea was to ease this burden by creating a smart meal planner that supports families in organizing their weekly meals in a realistic and structured way. Through an individual and detailed configuration, the system considers the needs of each family member while significantly reducing daily cooking effort. The goal was to enable healthy, varied nutrition without turning food planning into a constant mental load.Realizing this idea required deep nutritional expertise, real experience as a mother, and the ability to translate both into a simple and intuitive digital solution. Together with our partner, we combined domain knowledge and technical responsibility to transform an initial vision into a reliable and high quality product that genuinely supports families in their everyday routines.
