Bajkowe Poddasze – from concept to a fully developed web and mobile application with a subscription system

About the project

Client:

Bajkowe Poddasze is an educational application designed for children and parents, offering access to fairy tales and engaging educational materials. The web platform features high-quality content created by a psychologist and educator, aiming to support the emotional and intellectual development of young children.

Project goal:

Web and mobile application

To create a complete solution – a web and mobile application – for streaming fairy tales and sharing educational materials for children.

Safe Interface for Families

To ensure an intuitive, safe, and visually appealing interface tailored to both children and parents.

Flexible CMS for Content Management

To design a flexible CMS, enabling the client to independently manage content (audio files, PDFs, categories, collections).

Store and subscription with access to the full library.

To implement a functional store and subscription system, allowing users to access the full library through a subscription model.

"My Attic" panel with Content Library

To provide a user panel – “My Attic” – featuring a personalized content library.

Customer experience

fireup.pro presents a rarely seen approach: full transparency, empathy, and attention to every detail, understanding the vision. Today, I have a cohesive set of tools – a mobile app, a web application, and a landing page – that not only meet my needs but also provide space for further development. I wish every creator such a partner.

From challenge

Key Challenges

Expert content in a digital edition

Translating the client’s expert knowledge into an accessible, technically refined platform.

Intuitive content publishing tool

Building a CMS system that allows for easy management of fairy tales and supplementary files.

Seamless access to resources

Ensuring a smooth user experience for browsing, purchasing, and using fairy tales and educational materials.

Different access models

Supporting multiple purchase paths – both without registration and through a subscription model.

UX and elements of play

Designing a personalized user panel (“The Attic”) where children can store their favorite fairy tales and materials.

Through the solution

Analysis and planning stage

Product workshops made it possible to precisely define the app’s structure and the needs of its end users – both parents and children.
Different user journeys were mapped – from anonymous one-time purchases of individual fairy tales to full subscription access.
A feature backlog was created, including fairy tale views, user panel, payment and subscription systems, and a content recommendation engine.

Technology decisions

A CMS allowing the attachment of audio files and PDF materials to individual fairy tales, tailored to the needs of the content creator.
Implementation of a payment system with monthly subscription plans (with future plans to expand into annual models).
Development of an email reminder system for upcoming subscription expirations, along with an invoicing system.
A responsive front-end architecture, enabling seamless use on both desktop and mobile devices.

Implementation

Admin Panel: Enables adding and editing fairy tales, attaching audio and PDF files, and managing user accounts and subscriptions.
Store: Includes a categorized view of fairy tales and collections, the option to purchase individual tales without an account, and a discount code system.
Subscription: Automatically assigns new content to subscribers’ accounts, with a “My Attic” panel showing their favorite tales and materials.
Security: Payment mechanisms meet security requirements and comply with current standards.

From problems to solutions

Complex content relationships: Fairy tales needed to be linked with additional educational files (PDFs), which required a custom approach in the CMS. A flexible data model and tailored admin views were implemented to address this.
Diverse purchasing paths: The application supports both anonymous and registered users. Conditional logic and separate purchase flows were implemented to ensure a consistent user experience for both groups.
Audio playback on mobile: Issues occurred with background playback. The team decided to implement a native audio component, significantly improving stability.
CMS usability: The admin interface had to be accessible for a non-technical user. Through usability testing with the client, simplifications were made and the process of adding fairy tales was optimized.
