Ok when it works. Love the idea, but it frequently changes audio output from bluetooth to speaker while on calls. Since the most recent update, it's signed me out. The app seems to not work with my (very common) password manager to log in. Motorola just bought the company so they'll probably ruin it like they have done with every other aquisition of a decent product.

This app is great for the most part. But lately every time I try to use it, it has a horrible connection so the people I'm trying to call can't understand me. So it's been pointless to use it. If they fix the problem, it will be 5 stars.

I'm using a Samsung s20 ultra on AT&T firstnet. I'm a premium subscriber and everything works fine except for the option that I have turn on for the make calls as law enforcement however on many tests to different carriers and phone thar have caller ID the app does not send the law enforcement caller ID. Just the phone number and unknown caller with the city in that area code. Please fix or advise if others are seeing this or if it's working.

App is useless now, I get an error everytime I try to use it. I've been using g it for nearly 4 years and whatever they updated killed the app.

About this app

Free 10-21 app users can:
- Call citizens from local numbers
- Receive and respond to callback requests
- Direct citizens to dispatch for immediate assistance

10-21 Police Phone Professional subscribers can:
- Set your outbound caller ID to "LAW ENFORCEMENT"
- View the citizen's caller ID in callback requests
- Send an automatic follow up message via SMS
- Retain call records for the life of your subscription

10-21 (radio code for "make a phone call") is a Police App for making free* calls to citizens that GET ANSWERED. Calls are made from local (not blocked) numbers without revealing your personal number. Stop getting sent to voicemail!

For example, if you call a citizen in Miami area code (305), they will receive an incoming call from a local (305) number, regardless of where you are. They are more likely to answer that call on your first try.

If the citizen calls back, rather than bugging you off-duty, they will be prompted to "Press 1 to Request a Call Back" (via Push Notification) or "Press 0 to Reach a Dispatcher" (connects to a non-emergency number that you provide).

When citizens request a call back, you receive a Push Notification on your phone rather than a phone call. At your convenience, simply tap the notification to initiate a call back out to the citizen.

*Calls are made over a VoIP data connection and do not use your cellular minutes. While the data used is minimal, data usage fees from your provider may apply.
