Great for company, group and individual chats


Slack provides you with the ability to have company-wide chats (not recommended for medium or large companies), team chats, group chats with people from different teams or companies and chats between individuals. It is as secure as you make it, so be aware of the chat group settings.

I found it easy to use and the Support staff were very responsive and helpfu: 5/5.

Missing basic features..

Some bloke off the internet..

Slack as a service is useful (though way overpriced if you need a paid plan), but the app is nothing more than a web portal, and it misses basic features.

It takes up way too much screen space and has a huge left side bar which you can’t hide or minimise even though most people in a single team will have no use for it 99% of the time.

I need a small chat window that can sit unobtrusively at the edge of the screen, it’s simply not possible to do this with Slack as it takes up way too much screen estate.

Excellent app, but I think High Sierra has broken it.

This is my app store nickname

Normally excellent; reliable, quick, fully functional etc. Upgraded to High Sierra and now it’s fails to open. (This is not the only thing that doesn’t work on High Sierra, don’t upgrade (yet) kids, it’s a trap!)

Developer Response

We're so sorry about the trouble using this build with High Sierra! If you could write to us at, we can share a workaround. Thanks!
