Note: "Continued use of GPS running in the background can dramatically decrease battery life." This App is a companion feature to the IamResponding system, which enables first responders to know who is responding to an incident, where they are responding, and when. This is used by fire departments, EMS agencies, police agencies, and many incident response entities and teams. The IamResponding system also includes text and audio incident notifications from CAD and/or from live pager audio, duty crew scheduling, inter-agency messaging, live chat, incident mapping with directions, mutual aid connections and information, pre-plans, customized information displays, NFIRS and other incident reporting, and much more. This App brings many of the primary features of the IamResponding system to mobile users in the field, in an easy-to-use and access format. **Please consult the QUICK START GUIDE provided to your department/team to correctly enable all of the app functions and notification features. If you do not do so, some features will not work correctly** **You MUST be a member of an entity with a current IamResponding subscription in order for this app to work** We do NOT monitor the Apple App Store for technical support issues, and we cannot reply to support issues posted as user reviews. **For any technical support needs or inquiries, please submit a Support Ticket (https://support.iamresponding.com/hc/en-us/requests/new). Please Note: If your dispatch messages are not currently processed through your department’s IamResponding system, that is a free configuration that can be done in almost any jurisdiction, and is included with your department’s IamResponding subscription. Your app will have more complete functionality if we enable that feature for you. Have your local system administrator submit a Support Ticket (https://support.iamresponding.com/hc/en-us/requests/new) to set this up.
