These top three VoIP apps for Android allow you to speak with friends and family online. HushCrypt, Cryptify Call, and Silent Phone provide VoIP service, whether in person or if you live far away. Most of the time, it’s over Skype. But nearly every day on the news, there’s always a story about how some government agency has collected masses of data or spying on people.

Because of this, people want to know that their private lives are private and that their conversations with loved ones aren’t going to be kept as a record that anyone can view.

So if you have an Android phone and you want to make sure your calls are secure, then check out our list.

The best VoIP apps for Android:

HushCrypt

HushCrypt is one of the top mobile applications which allows registered users to send and receive encrypted phone calls using an internet connection through either WiFi or 3G. Both persons involved in a ring must have the HushCrypt application installed and active on their phones to talk securely. This is one of the downfalls because if you want to phone your mum, she’s most likely not to have the app or most likely not even have a smartphone, so you’re left without a secure call.

Signing up for an is very easy, and it’s also free of charge, so once all that’s complete, you can start phoning anyone you want securely. The data stream between two users is encrypted using the AES algorithm (using a 256-bit key length), and a new key is generated for each session. The exchange of the keys is made between users’ mobile terminals without involving any 3rd party.

Cryptify Call

A company that deals with sensitive information always needs to find the best ways to protect their work, so losing some vital information to a hacker heard over a phone call could be devastating for that company. With Cryptify Call installed on your Android, you can have sensitive conversations without having anyone intercepting your calls. The technology used in Cryptify Call combines state-of-the-art mobile communication technology with military-grade cryptography. Cryptify Call works home and abroad using either 3G or WiFi.

Cryptify gives you exclusive control over everything. Highly sophisticated encryption algorithms are used to create and distribute encryption keys. Using Cryptify Call is as easy as making an ordinary call. Yet, it provides you with the confidence that the call is both encrypted and authenticated peer to peer while at the same time experiencing high-quality sound with low latency during your secure calls.

Silent Phone

Silent Phone is one of the most secure globally encrypted video and voice calling apps you can download right now for Android. Before you can start using the app, though, you must be a paid Silent Circle subscriber to call people securely.

When a Silent Circle subscriber makes a phone call and sends a text or video chat with another Silent Circle member, that transmission is secured and encrypted from their iPhone, Android device, iPad, or PC on Silent Circles’ crystal transparent, secure network. Silent Phone utilizes the open-sourced ZRTP encryption protocol invented by Phil Zimmermann and Jon Callas and is currently being used worldwide for the best security when keeping voice and video calls secure.
