What's the best Android app for listening to live emergency service radio communications?

Police Scanner is a well-regarded option for accessing live public safety radio communications on an Android device. Its primary strength lies in its extensive and reliable database of live audio feeds from police, fire, and EMS departments across the country. For individuals such as hobbyists, journalists, or residents wanting to monitor local activity, the app delivers continuous, real-time audio with generally clear reception, though stream quality can occasionally vary by location and department infrastructure. A standout feature is the integrated code glossary, which deciphers the 10-codes and other signals used by officers, allowing listeners to better understand the nature of ongoing incidents.

Beyond the live streams, the app functions well as a background audio source, continuing to play even with the screen off, which is a practical feature for extended monitoring. User reviews frequently commend the developer's responsive customer support, particularly in resolving subscription issues during device upgrades. The free version provides substantial functionality, though a subscription removes ads and unlocks certain premium feeds. A minor drawback is that the level of 'action' is entirely dependent on scanner availability and activity in a user's chosen area; some rural or restricted channels may not be available. For consistent, ad-free listening with helpful context, the premium tier is often considered worthwhile by regular users.
