Delta Chat is the premier waiting room to be in until the big boys end their chat app/protocol wars. What does it do? It turns your email into a full blown chat application. Yes.. it’s an email messenger.
I was finally able to smoothly convert my last Signal contact. To persuade others, first prioritize email communication — ruthlessly. Then say: “Who in the world wants 10+ chat apps to talk to everyone?” If there’s agreement — you win ;-)
Supports: iOS macOS Windows Linux
