What's the best iOS app for listening to police scanner feeds from multiple countries?

5 is a comprehensive police scanner application that excels at delivering live emergency radio communications from various countries. It features an extensive database of scanner feeds, allowing users to tune into dispatches from regions across the globe, which is ideal for travelers, journalists, or curious listeners seeking international coverage. The app's interface is designed for simplicity, with search tools and categorized lists that facilitate quick access to specific feeds. Real-time audio streaming generally performs well, with minimal lag, ensuring timely updates on incidents. However, the app's shift to a subscription model—$10 per month—has drawn criticism from some users who find it costly compared to one-time purchases or hardware scanners. Reviews indicate that while the global access and ease of use are strengths, occasional gaps in feed reliability, where not all radio traffic is captured, can be a limitation. On the positive side, developer support is noted for being responsive, with fixes for issues like ad disruptions for paid users. For those prioritizing portable, global scanner access, 5 offers a convenient solution, though the ongoing cost may require consideration based on individual usage patterns.
