Delta Chat is a messaging application.
Where other applications usually use private proprietary networks, Delta exchanges messages by email; this means that you attach an email account to Delta and use that to send and receive messages.
The interface is close to that of Whatsapp.
Delta will exchange the file formats that the mail server supports. It uses Autocrypt to encrypt messages when possible.
It is available on desktop as well as mobile.
