Target Zero is a comprehensive iPhone application designed for tracking safety activities on construction projects. It offers a range of features including incident tracking for recordable injuries, observations of safety issues, recognitions for positive safety efforts, and violations of safety policies. Users can track activities by job, specifying the building, floor, and area, as well as by the affected user such as contractors, subcontractors, and owner team members.

The app utilizes OSHA safety codes to ensure compliance and automatically generates alerts for incidents involving bodily injury or lost work time. Each activity can be assigned a status of Open, Closed, or Overdue, and users can add comments and communicate with relevant parties to enhance and uphold a safe working environment on construction sites.
