Yapper is a language learning app focusing on real life application and conversation. It utilizes social media and slang to allow users to learn practical terms and phrases used in real conversations. Yapper launched on the app store in March 2025.
Problem
All that Duolingo and still no Spanish?
Most language apps prioritize grammar drills and formal phrases over how people actually speak. The result is learners who can read a textbook but freeze in real conversation. They lack exposure to slang, cultural context, and the natural flow of everyday speech.
Research
Why Traditional Methods Fall Short
Surveys and interviews with 1,600+ language learners uncovered a clear disconnect:
49.5% struggle most with speaking, yet most apps prioritize reading and writing
60% prefer speaking and listening practice, while grammar overload slows down
31.4% of learners who want practical usage instead

User Interviews
Real Challenges in Language Learning



Traditional apps over-index on grammar and structured lessons, neglecting the methods learners actually respond to like music, film, and real conversation. The next step was designing an immersive experience centered on practical, conversational language that reflects how people truly speak.
Design Process
Ideation
Grounded in our research, early wireframes focused on real-world immersion — exploring ways to integrate media, conversation prompts, and AI feedback within an intuitive, engaging interface.

Moving to high-fidelity, we refined the design to ensure smooth navigation, minimal friction, and an immersive, social-driven learning experience. Our goal was to remove barriers to fluency by making language learning effortless, interactive, and deeply connected to real-life use.


Solution
Yap and Learn Real Conversations
Yapper immerses users in real-world content like slang, cultural nuances, and everyday phrases — learned naturally through social-media-style scrolling. AI-powered speaking feedback, instant flashcards, and gamified games keep practice engaging, making language learning feel less like studying and more like living the language.
