Duolingo Math UI design & app screens

A standalone math-practice app from the Duolingo team, aimed at kids building arithmetic fundamentals and adults brushing up on mental math. Lessons are short, gamified bursts of problem-solving with immediate feedback.

The interface carries Duolingo's signature playful tone: rounded sans-serif type, bright color blocks, and the expressive owl mascot guiding progress. Notable patterns include the bite-sized lesson cards, the celebratory completion animations, streak counters, and tactile interactive widgets for tracing numbers, splitting fractions, and manipulating shapes directly on screen.
