Signal

Signal is an open source instant messaging app developed by Open Whisper Systems which can help you to have secure and private conversations with other users of this free tool.

Is Signal secure?

If you are wondering if Signal is secure, the answer is yes. Signal's first security measure is seen when you run the app for the first time. Here you will not have a separate login, user account or password, as this encrypted messaging app uses only your phone number and contact list. As a result, identity theft is highly unlikely.

Advanced message protection

Signal also uses an end-to-end encryption protocol that protects any message you send to any of your contacts. When in a private chat or group conversation, all messages will be completely private. What's more, just as with Telegram, not even the tool's own servers will have access to the information you share.

Attach other files to your conversations

As we have come to expect, Signal allows you to send all kinds of files in your conversations. Simply select photos, videos, documents or audio files to share them with your contacts from the chat window. All your files will be protected under the same protocol as text messages.

Video calling through Signal is now possible

Signal also offers you the chance to communicate with your contacts through video calls. With HD video quality, a good Internet connection is all you need to chat with anyone via your smartphone's camera.

Download the Signal APK for Android and protect your privacy by installing this secure and ad-free messaging tool. Thanks to the latest encryption technology, you will find this communication app provides you with an extra layer of security compared to other well-known similar apps such as WhatsApp and WeChat.
