I don't really understand... Does WhatsApp have a better UI? Why? To me signal is the best UI, and WhatsApp looks like a child designed it. Especially with the horrid default colors and backgrounds. But I don't really see a difference in UIs in most chat programs. There are only two types of UIs. Point-to-point (signal, WhatsApp, imessage, etc) and room based (irc, matrix, slack). Their all so similar, I don't understand what is better or worse in Signal compared to WhatsApp.
