Slack

Nice interface, very intuitive and easy to use. Facilitetes communication between team members, allows for creation of group chats, channels. It comes with a great and well customized mobile version as well.

It tends to get a bit slow at times, though.

Pros: I liked how user friendly and easy it was

Cons: Maybe too informal and not professional looking

Pros: Easy to use and chat with different people in group. Good multi chat functionality.

Cons: Sometimes it slows down with large number of chat windows.

Pros: It's ability to bring all the users from multiple organization to a single platform for communication

Cons: Its lack of support to set up meetings and in call support

Pros: - Ease of communication with my colleagues

- Availability of the same workspace on both desktop and mobile

- Highly customisable (emoticons, gifs, starred people)

Cons: The mobile version isn't as easy to use as the desktop version, takes a bit more digging into to find the same options. Took some getting used to a new logo too.

Overall: We use Slack at work every day, it's very customisable, great way to create polls, customise emoticons, create channels and closed chats that you can archive easily when they're no longer necessary. You can find parts of conversations easily and it's fun to use (people can add their quotes that appear when you launch the app).

Pros: Slack gives me the ability to communicate with all my team members in a timely and organized manner.

Cons: Digging through the old archives can be challenging but other than that everything is quick and easy

Pros: I really like Slack and think that it is easy to use and very efficient.

Cons: I really like this software, but sometimes it is very slow or it crashes.

Overall: I've really liked using slack and think it is something I will continue to use.

Pros: I really like the ability to organize groups by different channels so I can keep different groups I work with separate. This software is great for development teams as it makes it extremely easy to share code and make edits to code with a group. It is also excellent for notifying a group of team activities.

Cons: I do not like the notifications of slack on my computer, I am being notified of activity I do not care about at times and it makes it difficult to only filter important notifications.

Overall: Slack helps with collaboration especially in today's business world where so many workers are remote Slack helps my team to keep in touch.

Pros: Looks overwhelming in the beginning but is highly customizable. Works on every device out there and any platform from Windows, Linux, Android, iOS. Has great integrations with other applications like Google Calendar, Google Drive, Salesforce to help manage better the team workflows.Allows using channels for different conversations with clients and team members and direct messaging for privacy. The free version although is very limited, it is by far a much better communication option instead of using emails.

Cons: Requires a fairly big learning curve, but ones customized half the battle is won. Doesn't work without internet. I would still highly recommend Slack.

Pros: I like that Slack has lots of new features, compared to Google Hangouts. I was finding Google Hangouts to be ageing and they have not added any new features for a long time.

Cons: I dislike that there is no way to have a large print version of Slack, as increasing the zoom size in my browser breaks the styling.

Overall: We use Slack for internal company chat, when we want to send instant messages to each other. For all the time I've used it, I've found it to always be reliable, and fast, with no downtime. I appreciate that there are lots of new features, like emojis that we use as acknowledgements, and the ability to download and search all our chat messages. I have to recommend Slack.
