I have very little time each day to learn new words and need a quick way to review vocabulary.
It’s hard to remember words without context – I often forget them.
I want to learn my own words and topics, not just pre-made cards.
Sometimes learning words one by one gets boring; I like it better when I see them in different sentences or situations.
It would be great if I could set my own learning goals.

Pain Points
Limited time to study every day.
Difficulty remembering words without context.
Pre-made decks don’t always match personal interests or needs.
Learning can feel boring or repetitive.
Apps can be overwhelming with too many features or complex interfaces.
“Sometimes I just want to look through words and see how they appear in different situations—it keeps it interesting.”
“I prefer learning that fits naturally into my day, without feeling like a big task.”
5 user interviews were conducted with people currently learning a new language.
The goal was to gain a better understanding of their learning habits, needs, and everyday challenges.
The interviews showed that many learners face similar difficulties, especially regarding:
Time management
Motivation
Long-term retention of new words
Onboarding
User can generate a vocabulary deck on any topic
Users can also browse and find suitable decks in the Library section.
User Testing & Results
Engagement Rate: 100% of usability testing participants highlighted the Scroll Mode as the most intuitive way to review vocabulary.
Task Success Rate: 80% participants successfully created a personalized AI-powered deck and started a learning session without any assistance.
Feature Adoption: 80% of users expressed a preference for starting learning with Scroll Mode and ending it with a deep-study Focus Mode session.
Onboarding Completion Rate: 100% of users successfully finished the setup and started their first lesson in under 60 seconds, proving the flow is fast and frictionless.
To validate the core experience of Vokabio, I conducted usability testing with 5 potential users (language learners). The goal was to evaluate the efficiency of AI-powered deck creation and the engagement of the new Scroll Mode.
Learning Words with Flashcards
Users have little time in their daily lives to actively learn new vocabulary.
1
Learning words without context makes them hard to remember.
2
Many vocabulary apps feel overloaded with features, animations, or effects, which can be distracting and stressful.
3
There is often little personalization, and users cannot easily add their own words.

Overview
Create a custom deck by adding their own words.
Onboarding flow introduces the app’s core features and then asks users a few key questions about their language, level, goals, and interests. This information is used to personalize the learning experience and tailor the vocabulary content from the very first session

Learning Modes
Fokus Mode
The app offers two learning modes to support different study preferences.
In Focus Mode, users learn words using classic flashcards. After completing a session, they can see clear statistics showing how many words they have studied and reviewed.
Scroll Mode
In Scroll Mode, users learn by scrolling through content where words appear in different contexts, such as short texts or dialogues, video or tests. They can filter the content (for example, only dialogues or only texts), mark words as learned during the session, and view learning statistics at the end as well.
Vokabio redesign successfully transformed a high-friction study process into an effortless daily habit. By integrating AI automation and familiar social media interactions (scrolling), the project achieved:
Efficiency: Reduced the barrier to entry, allowing users to go from "onboarding" to "learning" in under 60 seconds.
Retention Hook: Created a "low-effort" learning path via Scroll Mode, which participants found more engaging and less mentally taxing than traditional apps.
User Empowerment: Delivered a highly personalized experience where 100% of testers felt in control of their goals, levels, and learning style.
Conclusion: Vokabio proves that language learning doesn't have to feel like a chore. By prioritizing simplicity and speed, the app bridges the gap between "wanting to learn" and "actually learning" in a busy everyday life.
