Duolingo struggles with inconsistent daily engagement and high drop-off rates, especially among busy users who intend to learn a language but can’t find dedicated time in their schedules. While the app is designed for short lessons, it still relies on users actively choosing to open it, which competes with distractions like social media, messaging, or simply fatigue during downtime. As a result, many users break their streaks, lose motivation, and eventually churn.
