Scrambl3 is the first totally private mobile app for calling and messaging and it’s free!
It is more private and secure than WhatsApp, Signal and all other voice and calling mobile apps. There is no sign-up with Scrambl3: Just download the app, create your anonymous Scrambl3 username and start making free mobile calls and sending messages to your Scrambl3 friends and business associates anywhere in the world.

Scrambl3 is private, non-intrusive, and does not use your cellphone/mobile number, nor does Scrambl3 access your personal phone contacts (WhatsApp and Signal do). You can even use your iPad or Android tablet – WhatsApp and Signal can’t because they rely on your cellphone number for making and receiving calls and texts.

Scrambl3’s unique Virtual Private Network (VPN) Dark Internet Tunnel architecture design removes the public telephone system SS7 security flaw that allows hackers to listen to your calls and read your texts. Use your Scrambl3 username on as many mobile devices as you wish because Scrambl3 does not identify you by your cellphone number, just your anonymous Scrambl3 username.

For complete transparency, Scrambl3 employs only open source software components
for encryption algorithms and Internet protocols and your Top Secret-grade VPN.

Here are examples of sensitive information that Scrambl3 is designed to protect:

* Business Executives in highly competitive, high-stakes industries
* Insider information (Publicly Traded Corporations)

* Create your Black Book listing of other Scrambl3 members. For the ultimate in privacy, only those persons can call or text you.

* A “Presence” feature tells you if persons in your Black Book are connected and ready to receive your secure call or text.

* You create a unique Scrambl3 name that is comprised of letters, numbers and special characters instead of a traditional phone number.

* Your Scrambl3 calls and texts take place within your own Virtual Private Network (VPN) and employees encryption algorithm and Internet protocol standards that are required for Top Secret Classified Communication.

* Your calls and texts are not stored on servers where they can be hacked.

* Scrambl3 calls and texts are free when using WiFi. You can also make Scrambl3 calls with a Data Plan from your wireless carrier, data charges from your carrier will apply only when non using WiFi.

Customer Reviews

Secure calling simply done right


This is exactly what we've been looking for on the iPhones of our corporate execs. Very easy to setup and use. Connected VPN automatically when program opens. Favorite part is the "Black Book" screen that lets you see who in your organization is online and even includes a built in secure texting feature. Nice.

Alone at last


Hello privacy...I've missed you! After reading a recent article about Scrambl3, I just had to get this app. It's straightforward to use and the call quality is impressive. The person on the other end sounds so clear and close to you. Hoping to see more features incorporated in the future.

Now more than ever, I appreciate the importance of Privacy on my smartphone. This App is super easy to download and use. The voice quality is amazing. It sounds like you are in the same room with the person you are speaking to. Highly recommended.
