Chat Clients

The ability to send text, voice, and video messages to anywhere in the world has never been easier. Simply fire up the messaging app of your choice, find the intended recipient that uses the same service, and start typing, attaching, and recording away.

If privacy and security are of the utmost importance, secure end-to-end encrypted messaging services such as Signal can ensure that the only people that know the contents of your conversations are exactly who you want.
