LockLeaf is an iPhone focus app that helps you stop opening distracting apps on autopilot. Instead of forcing you to delete social apps or rely on willpower, LockLeaf adds a quiz gate before scrolling. You can block distracting apps, answer quick quizzes, review flashcards, build streaks, earn XP, and turn screen time into a reward for learning. It is designed to make focus feel playful, intentional, and easier to keep.
