A friend and I downloaded Signal to try it out, and just couldn't get anything to work. I'm on iOS 8, the app would just crash anytime I hit any button to make an action (send a message, even delete my account). On his end (he was on iOS 9), it said it connected to me, but his messages just got lost in the ether in between us.

I mean, I'm a technical guy. I don't understand what either of us was doing wrong. Have you seen anything like this in your experience?

Why do you say that? Snowden keeps recommending Signal every time he's asked.

Telegram has better cloud sync. Signal doesn't have a desktop app AFAIK, only a Chrome plugin which is still in development.
