WHAT BUDGETING APPS, PELOTON, AND DUOLINGO HAVE IN COMMON

Summary from the TLDR Design newsletter

Many apps, like Mint, Peloton, and Duolingo, use the Hook Model — a psychological approach involving cue, action, reward, and investment — to build user habits. Features like streaks, badges, and progress tracking encourage engagement and long-term commitment, making these apps more enjoyable and addictive.
