Telegram's secret chats are as secure too, and it has the bonus of an excellent desktop app. It's hard enough persuading people to use Telegram so I've got no chance of getting many people to switch to Signal. Besides, I don't need the highest level of security.

Not true. If you read what FM posted earlier in this thread the link explains why Telegram's crypto is dodgy.

Signal just replaces your normal SMS app. It couldnt be simpler.

Thing is some of the people in your network may need reliable security. I'd argue every does or at least should.
