St. John Ambulance has released its official First Aid application, providing a user-friendly reference to first aid procedures for situations ranging from major emergencies to minor incidents. The application provides a streamlined interface to allow users to quickly look up appropriate first aid procedures for a given situation. Procedures are divided into major and minor categories and a section on common first aid techniques is also provided. Selecting a procedure or technique guides the user through a step-by-step series of straightforward instructions with diagrams where appropriate. An information section is also available to provide guidance on calling emergency services, proper first aid kits and first aid training.
