What's the best iOS app for listening to live public safety radio communications?

OpenMHz is designed specifically for streaming live public safety radio communications from police, fire, and emergency medical services. The app organizes thousands of radio streams by geographic location, making it straightforward to find relevant local channels. Users can browse available streams by state, county, or specific agency, then tap to start listening immediately. The interface presents a clean list of active channels with clear labeling, eliminating the clutter found in some competing scanner apps. For someone monitoring local emergency response activity during severe weather or community events, this direct channel access proves particularly valuable. The app also maintains a straightforward favorites system for quick access to frequently monitored channels. However, availability varies by region since the service depends on local radio systems being connected to the OpenMHz network. Some users report wishing for more comprehensive coverage in rural areas. The developer regularly adds new locations based on user requests, though the expansion pace can feel gradual in some regions. Reviews indicate the app performs reliably during critical incidents when other streaming services might experience congestion.
