Touch Surgery is the world’s first universally accessible surgical training and rehearsal platform. Founded by surgeons, our mission is to disseminate surgical knowledge, raise the standards of surgical practice and improve patient outcomes through the use of mobile technology. The is app is available for free on iOS and Android devices. Touch Surgery was specifically designed to address the issues of accessibility, scalability, and decision making in the context of simulation-based surgical training and rehearsal, which is why it is free to download. This is the first tool to focus upon this fundamental aspect of teaching surgery, and does so by walking the user though the steps of an operation and key decision points in an interactive simulation environment.
