Slack brings team communication and collaboration into one place so you can get more work done, whether you belong to a large enterprise or a small business. Check off your to-do list and move your projects forward by bringing the right people, conversations, tools, and information you need together. Slack is available on any device, so you can find and access your team and your work, whether you’re at your desk or on the go.

Use Slack to:
• Communicate with your team and organize your conversations by topics, projects, or anything else that matters to your work
• Message or call any person or group within your team
• Share and edit documents and collaborate with the right people all in Slack
• Integrate into your workflow, the tools and services you already use including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk, and more
• Easily search a central knowledge base that automatically indexes and archives your team’s past conversations and files
• Customize your notifications so you stay focused on what matters

Scientifically proven (or at least rumored) to make your working life simpler, more pleasant, and more productive. We hope you’ll give Slack a try.

What's New

Version 3.43

• Fixed: Videos uploaded from Slack on newer iPhones and iPads now play back seamlessly and correctly (and just as you might have always expected) on the Desktop app.
• Fixed: After tapping on a notification to read a message in a thread, the "All Threads" header remained bold, as if there was an unread message. Which there wasn't (or if there was, it wasn't the one you just read, because you just read it). We know. You read it. It all makes sense now.

Nice app, but I have to check the app regularly for updates. Should have notifications.
