Anatomy Flow helps you understand the body intuitively, ranging from entire systems to specific organs. The home screen displays your learning progress, current study streak, unfinished lessons, and quick access points to resume where you left off. You can browse the organ library—searching by name or filtering by system—and open detailed pages featuring illustrations, functions, locations, structures, and related organs. A rotatable full-body 3D model allows you to drag to rotate, pinch to zoom, and tap an organ to select it; individual organs also feature their own dedicated 3D views. Short, topic-based lessons guide you through the material section by section, allowing you to bookmark favorites and receive a congratulatory screen upon completion. Quizzes draw questions from specific systems or the entire database, featuring a timer, a pause function, and a results page for reviewing individual answers. Simulation scenarios place you in hypothetical situations where you select the appropriate organ or system, receiving a score, an explanation, and a streak count for correct answers. A "Fact or Myth" card set challenges you to evaluate statements and immediately view the explanations. The "Biological Clock" screen uses a 3D model to illustrate seven stages of a typical day—linked to active organs—alongside a full 24-hour timeline. Your personal profile aggregates progress by system, quiz history, favorites, and your badge collection. All learning data is stored locally on your device; you can toggle between light and dark modes, enable or disable animations, select your display language, or reset your progress to start over.
