Comments: It is so helpful to use with remote teams. I use it daily for two different employers, and actually convinced my main employer (a government agency) to start using slack. Slack allows teams to communicate easily and quickly, sharing links and documents all through the app. It also allows for camaraderie and fun, an important part of every workplace, even when you aren't physically with your team. The absolute most convenient thing about Slack is that you can use the desktop and mobile version, and someone can ask you a question, you can answer it, and work can move forward efficiently. For teams with people in different time zones and different work hours, this is incredibly helpful while texting and email sometimes don't cut it. For people who are outside of traditional cell service, sometimes I can connect to Slack even when text/calls are not going through.

Pros: I love how easy it is to communicate with people, and the informal format the encourages communication rather than dissuades it. People might be less inclined to send an email or call because they are interrupting your work, but slack doesn't have that feeling at all.

Cons: The limit on shared images after you hit a certain threshold with the free version - to be fair, this is a minor inconvenience at most and just another reason to pay for it!

Comments: Overall, Slack is a top-tier messaging application with a lot a fun and practical capabilities. The Slack mobile app is also very well built and user friendly, and integrates nicely with both Android and Apple operating systems. When compared to other IM applications we've used such a Google Hangouts or HipChat, Slack proves to be the superior and preferred interface in terms of both quality and feature capacity. I would definitely recommend this application for both business and personal use.

Pros: Slack has incredible integration capabilities, and can connect to a large percentage of other project management and operations software applications. Our of office, for example, we utilize its connectivity to Pingboard, JIRA, and Zendesk to make internal communication both thorough and seamless. It also has great external communications capabilities, and you can set up multiple teams with in a single application, and give each team its own individual permissions settings. On the lighter side, Slack offers fun and entertaining features such a giphy integration and surveys/polling, which are frequently used at our office.

Cons: Slack tends to have intermittent connectivity issues, which can be detrimental to workflow, especially if your company has remote employees. My company experienced several service interruptions over the past year, where Slack has gone down for multiple hours at a time, forcing us to resort to other means of communication (email, phone, Google Hangouts, etc.). The quality of Slack's call capability is also spotty, at best. I regularly choose other means of voice communication because I have consistent concerns about the audio quality of any given conversation taking place over Slack phone.

Comments: Overall It's a very useful app for little teams and big companies, you can manage your team/s with this app, beside chatting and conversation, it seems like you can visualise your work here with many addons. For example I have integrated github, jira, pivotal and these types of apps and can see notifications coming from this task managment tools in channel, like everything one place, event can call inside channel with hangouts app.

Pros: I like team workspace like design of app, especially the channels for teams, private channels, taggings by team, threads, and bots inside it which are very useful for variety of reasons, helping to increase users productivity and contributing for team to work fast.
Another thing seems to me very useful is integrating google calendar with slack which show to my teammates when I am busy or in a meeting or when I am free near my name on app.

Cons: Sometimes it has problems with mobile app push notifications, e.x many times I tried to reply message from push notifications but seems it not sends message showing could not send without notifying me. Another thing I noticed in recent times It has problems with video streaming, I mean when someone uploads video It sometimes streams very slowly .

Comments: All and all it's been good. I wish it were cheaper but it's not. For what it is though, Slack is an incredible communication tool that has been very reliable to us with no down time and no bugs.

Pros: First off we don't use any of the add-ons. They seem incredibly useful for those who need them but we just don't have the need. What we like about Slack is that it's simple and very fast. We used HipChat back in the day and liked that but once they got bought out by Slack we tried some Rocket.Chat and Microsoft Teams. In the end we had issues with both of these and decided to give Slack a shot. Slack is very simple and easy to use and is extremely quick. We constantly found the competition software would lag after as little as a month or two of use due to all the messages.

Cons: Price. Compared to the competition it's expensive. When Slack bought out HipChat we were initially bummed because our price per user was going from around $2 a month to $7 a month. As a company who doesn't use any of the add-ons this seemed a bit steep. All and all I would say it's still too expensive for what we use it for but the other options out there have issues so large we continue to use Slack.

Comments: Slack improves correspondence among colleagues. In spite of the fact that it doesnot supplant the need of email yet yes it clearly reduces unnecessary inside messages Slack stays a standout amongst the best group informing applications since it offers more than some other application in this classification. For a variety of devices and platforms, Slack is available: mobile Mac, Windows, Linux, Web, Android, iOS, and Windows.
It is a cloud-based tool in real time, so you need an Internet connection to use it regardless of which app you have.

Pros: What I truly like is to discover individuals and ping them and begin a transformation. Most significant, you can share records, photographs, URL, gifs (Very significant), in a solitary spot.
Making joint effort simple and something to appreciate.
at the point when significant data is imparted to other application it gets lost and there is no record of it. With the slack channel, the data is put away and can be utilized as references Slack makes it workable for its clients to have numerous alternatives of getting informed. The best component, as I would see it, is the place somebody can "@" you in a message or a post.

Cons: Below are some points which I least like in Slack: Video calls are just bolstered in the work area applications and Slack for web in the Chrome program. In the event that you join a call from a cell phone, you get sound as it were. So also, screen sharing just works from the work area applications, what's more, sharing control of screen sharing just works in the Mac and Window work area applications (not Linux). From the web application in Chrome, you can watch on the off chance that another person utilizes screen sharing, yet you can't start it. There is also no option for downloading conversations to create a hard copy record (for minutes of meeting, etc.). No File Preview: If you could preview a document without downloading it first, it would be nice. But Slack does'nt have this feature.
