Duolingo
App Redesign

A pitch for a more ethical, educational experience

Duolingo is the world's most downloaded language learning app — but beneath the friendly green owl lies a set of dark patterns that guilt-trip users, exploit streaks, and treat learners as a product. This redesign proposes an experience built on encouragement over pressure.

Duolingo App Redesign

Overview

What's Duolingo — and why redesign it?

Duolingo offers short, interactive language lessons and uses gamification to motivate learners. With over 500 million users, it's the most downloaded education app in the world.

But the same mechanics that hook users also manipulate them. This project asked: what would Duolingo look like if it put genuine user wellbeing at the centre?

The Problems

Three dark patterns holding users back

Through close analysis of the existing app, we identified design decisions that prioritize engagement metrics over genuine learning and often leave users feeling anxious, guilty, or manipulated.

01
Guilt-Tripping Notifications
  • "Nobody ignores me...for long. Do your lessons."
  • Countdown timers creating anxiety ("Last chance!")
  • Notifications designed to shame, not support
02
Streak Pressure
  • Pressure to maintain streaks at any cost
  • Streak Freezes sold as in-app purchases
  • Dismisses the real lives and schedules of users
03
Users Treated as a Product
  • XP leaderboards pit learners against each other
  • Ads shown after every lesson
  • Engagement-first design that values time-on-app over actual learning

Design Challenge

How might we redesign Duolingo so that users feel motivated, not manipulated — and actually learn a language along the way?

Storyboards

Before and after — Anjali's story

We created storyboards comparing the old and new experience through a shared user scenario. Anjali is an international student who needs to learn French for her Permanent Residency application, she's already anxious and under pressure.

In the old Duolingo, streak pressure and XP anxiety cause her to abandon the app and fail her exam. In the redesigned version, the app meets her where she is and supports her at her own pace, she passes.

Main Focus: Emotional Pressure

Five targeted solutions

Rather than overhauling the entire app, we focused on the features causing the most emotional harm — and redesigned each one with care, flexibility, and user wellbeing in mind.

🔔
Notification System
Three tone settings — Neutral, Gentle, and Strict Duo — let users choose how they want to be reminded. Notifications feel like friendly nudges, not threats or taunts.
📋
Lesson Recap
A judgment-free recap appears at the start of each session. No XP pressure, no punishment — just a low-stakes warm-up that eases users back in and reinforces past learning.
🎯
Goals & Progress
Users set their own learning frequency — daily, weekly, or custom. Session lengths are adjustable. Progress is tracked positively as points earned, not streaks at risk.
🪶
5 Feathers System
Replaces the punitive "lives" energy system. When feathers are lost, users do a focused repair lesson — learning from mistakes rather than being punished for them.
👥
Friends & Social Space
Shared goals with friends replace the competitive leaderboard. Healthy motivation instead of comparison — it's more fun to learn together than to race against strangers.

Style Guide

Staying familiar, feeling better

To maintain familiarity, we kept Duolingo's primary brand colours. In keeping with the redesign's more encouraging emotional register, the typeface combination of Feathers (bold headers) and Quicksand (body) maintains a warm and welcoming tone.

Final Design

The redesigned experience

The high-fidelity prototype brings all five solutions together. The visual language stays true to Duolingo's familiar character — same green owl, same playful energy, while removing the features that cause harm.

Reflection

What this project taught us

This project aimed to question the principles embedded in a design system rather than just enhance a user interface. Duolingo's dark patterns are intentional product choices that put user engagement ahead of user welfare; they are not coincidental.

Working as a team let us stress-test our assumptions about what "motivating" design actually means. The biggest insight: users don't need more pressure, they need more trust, flexibility, and genuine encouragement.

01
Gamification Can Harm
Game mechanics are powerful and that power can easily be turned against users. Ethical design means asking who benefits from each mechanic, and whether that benefit is mutual.
02
Flexibility Builds Trust
Giving users control — notification tone, session length, goal frequency, reduces anxiety and increases genuine engagement over time.
03
Focused Redesigns Do More
We didn't rebuild the app, we targeted the five features causing the most harm. Intentional, focused redesigns often create more meaningful change than full overhauls.
