Interactive English learning — one card at a time.
We took a proven physical flashcard system and rebuilt it as a modern mobile app for iOS and Android.
About the project
From a card box to 1,200 subscribers.
Angolutca had already validated the concept: physical English-learning flashcards with a loyal subscriber base. The brief was to take what worked in print and rebuild it as a native mobile experience — without losing the tactile, satisfying feeling of flipping through cards.
The new app needed to do things a physical card can’t: play audio for pronunciation, quiz users, track progress, and reach people anywhere.
The Challenge
From physical to digital — without losing the soul.
The physical cards had a format users loved. Digitizing them meant more than scanning — every card needed audio recording, phonetic markup, Hungarian translation, and category metadata. Doing this at scale for 1,000+ cards required a structured content pipeline, not just development work.
The second challenge was the quiz system. Users needed immediate feedback — not just “right or wrong,” but a response that felt encouraging, not punishing. Designing that feedback loop carefully was as important as building it technically.
We started with a design sprint — mapping required features, defining the card data model, and establishing the visual language. The app needed to feel native on both iOS and Android while maintaining Angolutca's brand personality.
1,000+ cards needed audio, phonetics, translations, and category tags. We built a structured content management workflow so the Angolutca team could populate and maintain the card library without developer involvement.
Built with React Native for true cross-platform coverage. Express.js powers the backend — lightweight, fast, and exactly the right scale for the product. The architecture was kept deliberately simple so the client team could own it going forward.
The quiz system required careful UX thinking: multiple choice timing, immediate visual feedback, streak tracking, and a results summary that motivates rather than discourages. We iterated on the feedback states more than any other part of the app.
The Result
Learn from anywhere.
iOS and Android from one codebase
Native audio playback for correct pronunciation
Quiz answers scored and explained in real time

One question. Just like the app.
What does "umbrella" mean in Hungarian?
