Heart Pro III is an educational and reference app developed by 3D4Medical.com in collaboration with Stanford University School of Medicine. It is a comprehensive tool for learning about the human heart, featuring detailed 3D animations and interactive features.

The app offers a wide range of features, including a 360-degree rotation of the heart for a complete view from any angle. It also includes animations that demonstrate various disease states, which can be purchased separately. With 19 free animations and 51 available for in-app purchase, users can explore different aspects of the heart and its functions.

Heart Pro III also includes two types of quizzes, Drag and Drop and Multi-choice, allowing users to test their knowledge and reinforce their understanding. Additionally, the app provides audio pronunciations for every label, making it easier for users to learn and remember the correct terminology.

One of the standout features of Heart Pro III is the ability to draw on any screen image and share it through email, Facebook, or Twitter. This allows users to annotate and discuss specific areas of interest with others.

The app has undergone several improvements, including graphical hints for better understanding, a rebuilt interface for simpler navigation, and the option to mix layers and make them semitransparent for comparison. It also offers a public notes feature, where users can share and browse through shared notes.

Heart Pro III is not only a valuable tool for students and healthcare professionals but also for physicians, educators, and professionals who can use it to visually explain conditions, ailments, and injuries to their patients or students. It serves as a comprehensive learning and reference tool that can be customized to different levels of expertise.

Please note that Heart Pro III is not compatible with 3GS iPhones.
