Swift911 Public is a free mobile application designed for iPhone users, enabling them to receive vital emergency alerts from local authorities and businesses. By leveraging the Swift911 Alerting Platform, this app allows users to stay updated on emergencies that may impact their safety, provided their area is serviced by a Swift911 account. The app's registration process is straightforward, allowing users to opt-in for alerts from their town, city, or other subscribed areas, including locations where family or secondary homes are situated.

The app utilizes GPS technology to notify users of nearby emergencies, particularly at public venues, while also offering the option to disable location services. Users can customize how they receive notifications, choosing from voice calls, emails, or text messages. Additional features include the ability to inform emergency personnel about specific needs and attach home photos for quicker identification during emergencies. Voice alerts can be accessed within the app, and users can view email and SMS notifications directly through the platform.
