After a brief mental shift from plain IM and adjusting to the idea of this being more of a chat for groups, I really like it. Would be nice if you could connect to individuals outside of joining a team, as well. My only other complaint is that I don't always receive notifications.

This is an awesome tool. I collaborate with a couple of different companies and groups and staying on top of issues, trends, and activity between all these would be extremely difficult if I didn't have access to slack. The newish /remind feature is awesome. So many tools available in this product and from my experience with this product over the past 1.5 years I see more useful features coming! Simply awesome!

Excellent app, everything is simple and straightforward. Slack just keep it this way and you're golden.

It's amazing to keep track on the team and focus on specific areas of the project and not have one chat for different conversations. DO NEED VOICE MESSAGES THOUGH!!!

Excellent iPhone app, makes Slack a breeze on the go on both iPad and iPhone. Simple to use. Has really helped with being effective away from desk, out and about. One of the best i-apps I've seen. I highly recommend it if you use Slack!
