For the "irc is just as good as Slack, you should just use irc" crowd, Slack's mobile clients are pretty good. Ever tried to get a non techie person to use irc on a mobile device? Ever used irc on a mobile device? The experience is terrible.

Slack's clients also have persistence, as in shows the most recent history of communication.

Not everyone uses screen/tmux with irc (though they should).

I hate this argument. Yeah, IRC is open and there are tons of clients for it, but Slack is the only one that I've used that a) retains history without you having to think about it, and b) is actually really really REALLY nice to use.

That said, if all you need is simple team communication, IRC works great

Try palaver on iOS. It's pretty seamless if you don't know much more than a server address.
