I like this app and was first introduced to it when I joined a technical support team. It is fast and reliable and has a nice interface which is easy to navigate.

I liked it because it has this great feature of integration with other software like google drive.

Love that it's user friendly and was very easy to set up. It is real easy to communicate with other team members.

Slack is refined, clean, and very user friendly. It integrates with many other tools in our stack and always offers a great experience.

The different channels help to keep conversations organized. The fun features make this instant messaging fun and add flair.

When te connection is down, the messages stay grey and after some minutes, they fail, so sometimes the internet connection come back and those failed messages are sent after the previous ones.

Overall, I'd say that once a company is used to the mechanisms and abilities of slack, it has the potential to do a lot of good. Once comfortable with it, it is quite efficient and enjoyable.

The best thing about Slack is the ease of use and the ability to communicate quickly and effectively across multiple teams/projects.

I love the feature that allows you to pin links to the header of a channel making it easy for others to access certain documents. In addition,  The Slackbot is a great help tool.

It's really useful, practical and easy to use. Great way to communicate and even fun because you can add your own emogi and use giphy.

It is super user friendly and able to navigate through the platform with ease. It has been money well spent and has helped our business flourish.

I recommend it to everyone I know. More people should use it! perhaps invest more on marketing so that it is more popular among crowds.

The best thing about this software is its easy to use and very useful functions. I love being able to select groups to notify or send announcements easy, essentially getting rid of email.

The only thing that I dislike is that I can easily get distracted by the notifications.

What is nice about slack is that you can have multiple channels based on what the communities interests are and that tagging people in messaging is really helpful.

After working in companies that used popular but non ideal instant messaging apps, having a solution as Slack for messaging the team is a lifesaver.

This software is the best source of communication because here are chatting opportunity is always free and reliable.

Allows superb enterprise-level communication. Integrates with other software seamlessly and allows productivity to be maximized.

It has been a great experience, and customer service is helpful and friendly. It is the perfect software to keep in touch given the difficulties of 2020.

Overall it's good, fast and very user friendly once you start using it you will love this app.

Webhooks are incredibly useful. Custom emojis are great for teams to develop a fun atmosphere.

From keeping message history to other basic necessities, Slack charged for a lot of it. Comparing it to Discord, it cannot compete.

Super light and easy to use interface. Integration services with Google apps (Calendar, Sheets, etc) are excellent and seamlessly integrated into the conversations.

I love the look and how it is comfortable in the eyes. Functional in all aspects especially the integration with other apps that we use like Time Doctor and Asana.

You can easily confuse groups your in and comment something to the wrong team ( I've done it on many occasions) and confused the heck out of some coworkers.

Zello has been great in supporting our agency with free services. They are definitely doing great things.

Thank God for Zello, we are now able to communicate effectively.

I like most the connectivity and speed of the APP and software. Quick download, ease of use and easy setup of users are all highlights.

Been a great experience and we expect that to continue.

Great! highly recommended and saves a bunch over buying walkie talkies.

Connection issues from time to time. The volume has to remain on for communication so some have complained it can be disruptive in a client meeting or setting.

The most significant benefit for us was the accessibility via the API. While the web management console is easy to use our deployment depends on custom integration services.

We do have an on-premise Zello Enterprise server and the setup and configuration are straightforward and easy. Support from zello are superb.

We like zello a lot, but we are investigating at the moment possibilities to use gateways to combine zello with our own radios. This is especially an area’s imported, where we do not have internet.

But unfortunately, because it disconnects a lot, I sometimes miss messages or cannot send them.

Alarm needs to be loud (should wake up a person) and vibration is needed. We would also need a status panel, where status of the assigned job can be changed.

The range  is great and I like that you can playback messages. You can add your email account and works with pretty much and phone.

I saved a ton of money when I started using Zello. We drop our Verizon push to talk cell phone and also didn't require to use Walkie-Talkie devices either.

Overall I am very pleased with Zello. I rely on this software to ensure the safety of my officers.

Zello is super easy to use and train new employees on. It's easy to add users and make changes and the working with the zello staff is great.

There is a slight delay when you start talking to another user. It cuts off  a small part which at times you have to repeat yourself.

In our country radio frequency is paid and hard to receive license for using it.

As mentioned several times already, we would need a pager function similar to Group Alarm, Divera 24/7. If zello is inactive it is impossible to alert someone.

Also can be used when traveling with multiple vehicles. It is easy to use and great for communicating quickly.

The documented API is easy to use and the provided SDK's worked great.

I would say the only downside to this software is there is no gateway support unless u pay for it.

Zello helps our Search and Rescue organization to save lives. We don't have to repeat transmissions, and can have people participate from anywhere.

Zello also stores all missed and recent messages and alerts so users never miss important information when in the field. In addition to the PTT app, Zello offers a dispatch web app that allows dispatchers to manage a shared queue of incoming calls and relay calls and alerts to drivers and field workers.
