"I've been in law enforcement for 20 years and I have found a lot of apps that helped me do my job. However this one surpasses them all. Best law enforcement app yet." - NC Police Officer

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.
1) A new Premium feature, Cloud Contacts, for creating contacts specific to the 10-21 Police Phone app.
2) Fixes for bluetooth devices.
3) Other small enhancements and minor bug fixes.

Great app with great intention.
I did love the app. Worked great when I had data service, however had to stop using it. We are on a 2gb plan for 3 people in my family and unfortunately the app used enough data to get my wife’s attention. Yes I did use it for work related purposes, however I’m the one paying the cell phone bill. If the app used my normal cell service which is 1. Unlimited and 2. Normally still available in low data service areas....then I would still be using it today. Love the idea behind it, but can’t use it.
Most Useful App for LE
Having been in law enforcement for 16+ years, I’ve used everything over the years from dialing *67 before each call (leading to many ignored calls) to buying a second pre-paid phone specifically for work use, to the hassle of having dispatch dial numbers for me and connect me. The 10-21 app is by far the most effective and economical resource. Even with an agency-issued phone, it is still extremely useful in allowing me to keep my number private to avoid calls while I’m off-duty, busy at work, or becoming someone’s “personal deputy” whenever they need something after I return their call and expose my number. The app is user friendly and rarely has any glitches or issues. Highly recommend for ALL law enforcement officers, and I look forward to the upcoming premium version with even more features.
Great to use for patrol
Usually people who I contact via phone see a “no caller ID”. It is hit or miss if they answer or not. If they don’t answer they have to go through the hassle of calling our busy dispatch center, transferring the call etc. With this app, it actually gives them a random number to call back and it notifies you via the app. I find it very useful for patrol when your trying to do follow up or your RP just wants a 10-21 prior to responding.
When the RP calls back it even gives them the disclaimer, “ if this an emergency hang up and dial 911”. Thanks guys!
