No hardware. No cost. It works on Android and iPhone.
Keep reading to see the five best free scanner apps.
ℹ️ Important: In the United States, listening to public safety radio on open frequencies is legal for regular people. These apps are for awareness, not interference.
What a police scanner app does for you
A police scanner app streams the same live radio that police, fire, and EMS units use right now. You hear real dispatch calls, not recordings.
For years, this needed real equipment. People kept a Bearcat scanner radio, a Uniden scanner radio, or a Whistler scanner radio on a shelf. Those units cost $100 to $400 and had to be programmed by hand.
Today a free app does the same job and does it better. It fits in your pocket. It finds your local feeds by itself. And it can alert you when something big is happening nearby, even while your screen is off.
The real value is time. A local emergency scanner app can warn you about a fire, a crash, or a dangerous suspect in your area, often before it reaches the news. For an older adult living alone, that early warning matters a lot.
The 5 best free police scanner apps right now
Each app below connects you to live police, fire, and emergency radio feeds. All five are free to download and actively updated. Here is a quick view before the details.
| Broadcastify | Biggest feed directory of all |
| Scanner Radio | Best all-around pick for Android |
| Police Scanner 5-0 | Best for reading police 10-codes |
| Smartest Apps Scanner | Best at finding your local feeds |
| Citizen | Plain-English alerts, no radio codes |
Broadcastify, the largest source of live scanner audio
Broadcastify is the most trusted name in scanner radio frequencies. It is also the network that powers most other scanner apps.
The feeds come from real volunteers running actual programmable scanner radio gear across the country. What you hear is live, not simulated. That is what makes it the most complete public safety scanner app directory on mobile.
It covers police, fire, EMS, aviation, railroad, and weather feeds. Everything is sorted by state, county, and city, so you find your area fast.
How to get it: search for Broadcastify in the Google Play Store or the Apple App Store. It is free to download on both.
Scanner Radio, the best free police scanner app for Android
Scanner Radio is the most downloaded scanner app on Android and a top pick on iPhone too. It gives you access to over 8,000 live feeds.
The alert system is its best feature. When a feed near you jumps above 2,500 listeners at once, you get a push alert. That spike usually means something big is happening close by, often before the news covers it.
It runs quietly in the background with lockscreen controls. That makes it easy to use as a police scanner for vehicle listening or as an all-day home monitor.
✅ Tip: If you are new to scanner apps and use Android, start with Scanner Radio. It works out of the box with zero setup.
Police Scanner 5-0, the best pick for 10-code listeners
Police Scanner 5-0 is the strongest option for people who want to understand what they hear. Its built-in police code scanner guide translates every 10-code in real time.
So when dispatch says 10-33, the app shows you it means an emergency. That turns background noise into information you can actually use.
It carries thousands of live U.S. police and EMS feeds, sorted by state and city. It was updated in March 2026 for full Android 16 support, so it stays current as a police tracker app android choice.
Police Scanner by Smartest Apps, the best local police scanner app
This one is built for people who just want their local feeds fast. Open it, allow location access, and it surfaces the nearest county and city channels in seconds.
There is no browsing and no manual setup. It works as both a free police detector app and a simple situational-awareness tool.
It shines in smaller cities and suburban counties, where bigger platforms sometimes pull feeds from the wrong region. The location-first design keeps you tuned to the right place every time.
Citizen, the best crime scanner app for plain alerts
Citizen works differently from the others. Instead of streaming raw radio, it reads real-time 911 data and sends you plain-English alerts.
When something happens near you, a fire, a pursuit, a robbery, you get a notification with the location and live updates. In many cases you can watch live video from the scene.
For anyone who finds constant audio tiring or confusing, Citizen is the easiest tool on this list. It gives you the awareness of a police scanner that actually works with no radio codes to learn.
Who each police scanner app is best for
The right app depends on the type of listener you are. Matching the two makes a real difference in daily use.
Longtime scanner listeners
Best: Broadcastify or Scanner Radio
If you grew up with a CB radio police scanner or a handheld unit, these two feel like home. Same audio, no antenna.
Safety-minded homeowners
Best: Scanner Radio or Citizen
If you want to know what is happening two blocks away first, the alert systems in both apps keep you informed all day.
Total beginners
Best: Citizen or Smartest Apps
If you want awareness with no learning curve, plain alerts and automatic local setup are the way to start.
What these apps do better than old hardware
The clearest win is real-time awareness. A police fire EMS scanner app feeds you information as it happens, not filtered and not delayed.
The second win is police-code fluency. With regular listening, the 10-codes stop being noise. Apps like 5-0 speed that up with a built-in guide.
The third win is range. An old digital scanner radio only held the channels you loaded. These apps give you access to 7,000 to 9,000 feeds at once, and you can switch from your local scanner radio to a weather feed in seconds.
Emergency responders, neighborhood watch members, and everyday citizens have used scanner radio frequencies for this for generations. These apps carry that habit onto a phone you already own.
Common questions about the best police scanner app
A few quick answers before you download. These cover the doubts most first-time listeners have.
Which app is best for Android overall?
Scanner Radio. Its 8,000+ feeds, background playback, and alert system make it the most complete option for Android users.
Which finds my exact county best?
Police Scanner by Smartest Apps. Its GPS setup pulls the right local feeds the moment you open it, with no searching.
Is there one that needs no scanner knowledge?
Citizen. It sends plain-English alerts with no radio codes, frequencies, or setup to learn.

Any of these five is a solid free start. Pick the one that matches how you like to listen, install it, and you are set.
