Signal

Signal is one of the most secure messaging and communication apps in the world. This open-source tool developed by Open Whisper Systems has millions of users worldwide and is constantly providing more benefits. Remember that Edward Snowden himself lauded this tool from the very beginning.

It must be said that if you have never used Signal before on your smartphone, you do have to install the Android app on your device. After that, you can synchronize both devices and put all contacts in common.

One of the key elements of the Signal for Mac version is that you also can send photos, videos, and any files or documents that you want to send to the chat window. In the same way, the security encryption is excellent, and on the computer, you can verify the identity of everyone you are chatting to.

With Signal for Mac, you can take advantage of your computer's power and performance to have end-to-end encrypted conversations. With a simple and efficient interface, you can stay up to date with all your conversations without having to keep an eye on your smartphone all the time.
