Subdial is a mobile app developed by Big Human LLC that aims to provide users with alternatives to calling 911 in moments of crisis. The app is designed to help citizens resolve issues without involving the police, offering resources for mental health, domestic disturbances, non-urgent crimes, and more.

The app works by allowing users to download it and share their location or enter their zip code. They can then search for locally available resources using categories or keywords. The app provides detailed information about each resource, including descriptions, locations, phone numbers, and more. Users can save these resources for future use and contact them when needed.

Subdial currently serves several states, including Alaska, Arizona, California, Colorado, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Virginia, Washington, Wisconsin, and Wyoming.

By offering access to alternative resources, Subdial aims to create a network for people to find the help they need and empower them to help others in safer and more effective ways.
