The right tool for the job!

5.0 3 years ago

Comments: Best thing that happened to our company. Our productivity has increased since and our "reachability" as well. We feel very close now, even for our team which is 100% remote.

Pros:

They really put the work into making a chat software that is very usable. intuitive, agile and overall, very enjoyable. We use many of the bots the marketplace has, especially the Google Calendar, Zoom, Giphy and Slackbot integrations that comes with it.

Cons:

I cannot think of much of what I dislike about Slack, because I like everything about it. I used to have an issue that Slack didn't load properly, but an update and empty cache button swiftly solved it. Sometimes the calls ring on the phone first before doing it in the computer.

Slack – Managing projects optimally

3.0 4 years ago

Comments: Slack is a tool which can be used as a project management tool for managing projects and also it can be used for internal communication inside a project group or a company. Each project group can have its own channels inside the company workspace. Communication through private and public channels has made Slack more popular among the users.

Pros:

Slack can be considered as a project management tool. Slack provides both mobile version and desktop version applications where the mobile version is installed in the mobile phone so that whatever may be the situation user may not miss any important information about the project instantly. While the desktop version helps to transfer files of the working project easily while working on the project. Slack provides the facility to share the files, folders, audio and video clips, links. there are private and public channels in slack. Users can be added to these channels and if the users prefer they can have their own personal chats through slack. The emojis, stickers, GIF are also added In Slack to provide better user experience and attract the users with its familiar look to most of the social media or texting apps.

Cons:

In order to use Slack users need to have a proper network connection. Without proper network coverage, Slack won’t work. Sometimes messages won’t be delivered to the other side after a selected time(10 PM). Unless the user sets his or her state into active user won’t receive notifications after 10 pm. If the state is away then the messages sent after 10 pm won’t be delivered till the next morning. Because of this sometimes users may miss some important messages. It is both an advantage and a disadvantage too. There is no mechanism to know whether the receiver read the message or not once a message is sent. The sender has to wait until other messages come from the receiver acknowledging that the receiver read the message.

Discussing about pros and cons with features.

4.0 2 months ago

Comments: I am using Slack for the last 3 years in my daily life. It helps in my daily usage of communicating with my firm colleagues and work partner. It helps me in different in this period like audio calls, messaging, and sharing documents and files. The magic link feature is amazing. I think only a few apps or software have these types of features.

Pros:

I feel the most marvelous features in Slack are magic links, a separate channel, real-time messages, and notifications. Real-time messages and notification help to easily communicate with co-workers. Magic link is an easy way to access your account without email and password. It is faster as well and sometimes it is not necessary to remind email passwords. A separate channel is a secure way to access or have project discussions. It is also good in security ways by it have own URL to join its particular channel to those who are authorized. Due to this slack brings people together to work as one unified team

Cons:

Slack is a messaging app for businesses. One thing about being dissatisfied with slack conversations get deleted after 14 days, so if we sent something important within a channel it will erase so this feature kept me having difficulties at some sort of times.

Vital tool for team communications

5.0 2 months ago New

Pros:

We use Slack for the bulk of our communications. The ability to set up a range of channels helps teams focus on the topic that are critical to their work, and keep abreast of happenings in other areas of interest. The ability to use Huddles to quickly collaborate with teammates on the fly is super useful as well. Slack can be a lot of fun as well, it's a brilliant way to let workmates share there interests across a range of areas - not just those related to work!

Cons:

Slack regularly improve their tool, and recent updates to the way Huddles work have solved a few gripes I have there. My main suggestion is that voice chat could be more developed.
