What's the best iOS app for listening to live police and emergency scanner feeds from around the world?

Police Scanner + is a comprehensive app designed for accessing live police, fire, and emergency radio broadcasts from virtually any location. It stands out due to its vast database of scanner feeds, which includes thousands of sources across different countries. This makes it ideal for users who need to monitor local incidents, such as journalists tracking breaking news, hobbyists following public safety events, or residents staying informed during emergencies like storms or protests. Specific features like a searchable directory, favorites list for quick access, and real-time audio streaming enhance usability. Reviews indicate that users appreciate the app's ability to locate obscure or distant feeds, with one noting, 'I’m surprised you guys even find these.' However, some users report occasional interruptions from promotional prompts, which can be a minor annoyance. Despite this, the app's reliability and broad coverage make it a top choice for real-time scanner access.
