1: Simple Poll 

This app allows you to run a quick poll. If you format your post correctly — starting with /poll and adding the different poll answers in quote marks following your question — you’ll produce a quick poll that automatically offers “1”, “2”, and “3” options as clickable number emoji below your question, allowing your entire team to quickly come to a decision.

2: WorkingOn

Here’s how they describe it: If your team falls behind on projects or overlaps them too often, this app can keep everyone on track.

3: Marker

This app lets you easily paste a screenshot into Slack with just a few clicks. It’s great for teams that often need to quickly capture exactly what a customer is complaining about or just what a section of code looks like.

4: Tettra

This bot lets you build an internal wiki full of sensitive company information that you’ll want at your fingertips, but can’t risk turning to yet another new site for.

5: Google Hangouts

Every techies’ favorite free video call service (sorry, Skype) is available on Slack with one click: Just get this app and then type /hangout into a channel to produce a link that can take any other member of your team into an instant hangout to hash out a problem or just touch base.
