Kids Director

I was intrigued by the option to send audio messages to friends.

Writer

Gives me a separate app to use for work text exchanges.

Admin

You can select who receives your messages, and create different group settings, which is really helpful.

Call center

I love how I could use it to communicate with friends on the college campus and it was like a walkie talkie app which was really cute & fun

I loved the app, it was easy to use & easy to communicate with friends, you can see who reads the messages you send, it’s similar to a ‘walkie- talkie’  which was pretty cool but overall a very fun way to communicate with friends & family

Owner

the only "downside" is that the content is only available for 30 days on the free platform, but if you're using it the way I do and communicate that regularly to your clients it shouldn't be an issue.

Tech VA

I pay for an annual Pro subscription of Voxer - yet I have no access to these features because I am not an iOS user.  

Payroll Manager

Voxer will catch on very quickly and will be one of the best communication systems out there !

Bookkeeper 

Voxer greatly benefits me because It allows me to make long interrupted messages.  

Coach

I've experienced a couple of occasions where a client sent a voice note which couldn't be played at my end - a bug in the app at that point in time maybe?   

Sometimes these days are so busy, a phone call is hard to make so a voxer message is convenient to keep in touch with others.

The only feature that I don’t like is that you can’t edit your message once you start recording.

Architectural Technologist

It saves SO much time and my clients love using it too.

Founder

It’s something I hop on to without thinking, it just does exactly what it says it will do (which is allow for text of voice messaging) without fuss or frills.

INDEPENDENT SALES DIRECTOR 

I also would love it if it had a video option like other apps can do.  

This app has really helped me stay organized and on track with my business.

Realtor

It's so easy to use- and I like that you can either hold the 'button' like a walkie or push to start and push to end.

Community Manager

Great to communicate with your team, clients, etc. when you don't want to get onto a video or phone call, but it's too difficult to type out over email or slack, you can walkie-talkie them!

Chief Narrative Officer

Slack has a very similar tool, but it requires the PRO version. Until that's available in Slack for free, Voxer is the top choice for voice messages.

Founder, CEO

It is such a convenient tool when you can't express what you mean in writing and you don't have time to schedule a one-on-one call or meeting.

Life Coach

I have dropbox so it isn’t necessarily a problem, but I feel like sometimes you have to create too many profiles on things to get just one of them to work fully.

It's easy to communicate with clients & team members.

Co-Director, WNYTR

We had some privacy issues that came up where unknown users outside of our group were privately messaging a team member.

Through file and photo sharing, teams can collaborate and communicate.

Independent Sales Director

Overall, it's an amazing communication tool that combines voice and text based messaging.

I don’t like giving out my personal phone number so this is a nice platform to avoid needing to do that.

District Manager

What I like least about Voxer is that sometimes the messages aren't clear enough to understand.

It's a time saver because critical things can be communicated but without the time taken in conversations.

Graphic Designer

I love how I can connect with my clients and team verbally with a touch of a button.

It is also fun to chat back and forth with my friends at the push of a button instead of texting or calling.

I can communicate by voice without having to make a live phone call.

Nonprofit Strategist

Voxer is a great tool for quick voice or text messages.

This allows them to respond on their own time.

Life and Business Coach

The messages are saved so my clients and I can go back and listen or read what was said for easy reference. And, with the paid version, you can take back a message you didn't mean to send.

Advanced engineer

It is useful for jokes, but i do not use it as my main message app

Self Employed Rancer

The thing I like the most about this software is that you can actually listen to the message on the app.

I appreciate being able to forward content to other users.

Digital Designer

Just being able to talk back and forth while not in real time is so helpful!

Teacher/Coach

Voxer made communicating during athletic events easy and fun.  

They can send me voice messages and then I can collect my thoughts to give them the best answer before I respond.

I get so tired of texting sometimes and it's not always convenient.

Bookkeeper

One of the features I like the most on this software is being able to speed up voice messages.

customer care specialist

It would be great if voice to text transcription was for longer than 30 seconds.

It is slightly antiquated and I wish you could send bigger video files, but overall a good product to use

Open Source

Zulip

Linux

Chief of Staff

if you have a lot of channels & topics it can take a while to scroll through relevant ones or sometimes it's hard to find what I'm looking for, especially when it auto-collapses between DM and channels

Parts Manager

Teams crashed, wouldn't open properly and had to manually boot up the "old" version for it to work, it would randomly close in the middle of the work day or fail to show a notification so messages were missed.

Maintainer

There's a wealth of options for private and public channels, types of notifications and their behavior, and robust permissions.

Associate Professor of Pediatrics

The integration and automation options (bots/webhooks, GitHub/Zoom integrations) have streamlined our workflow.

Assistant professor

I have used it in small research groups around five people to coordinate joint writing and programming projects, in university courses I teach with a larger number of students, and in a large research community with thousands of members.

Operations Manager

We also wanted something that would allow for voice and video calling and file sharing, and the ability to post your status so that each user can see at a glance who is available.

The learning curve can be a bit steep for new users unfamiliar with streams and topics, but this is rare in the real-world.  

Ability to create additional folders and topics under a channel.

Scientific Researcher

I find very useful to group all possible topics that currently I'm working on with my team and mark as resolved the ones which seem to be done.

Board Member

We use the tool for communications between members of the management board and it allows us to avoid the well known "Respond to all" trap with conventional e-mail

Would love to get a proper "archiving option for topics, not just adding a checkmark.

Professor

Over the years I have seen software communities (mainly scala earlier) move between various discussion forums, always trying to tradeoff. With Zulip everything is essentially as it should be, allowing asynchronous coordination of workflows involving code and mathematics in an intuitive and clean fashion. Except for the phase when Gitter was well maintained, Zulip is the first forum which just works.

When discussing various topics, it would be nice to be able to reply comments in a separated box.

Likewise, typing of equations using LaTex commands works pretty well!

The biggest negative feedback we receive using the product is that it is up to the user to manually update a custom status, and custom statuses cannot be saved as a preset.

Inspector

Thanks to the threads and discussions, we can also use Zulip for some fun small talk on some subjects like we did on WhatsApp (gif and emojis) without cluttering the serious work space.

Because Zulip is a less common platform, most folks haven't used it before and have a bit of a learning curve to get fluent in it.

President

Channels with topics, custom emojis, email alerts, mobile app, push notifications

Sometimes takes time to load on mac after inactivity.

Software Engineer

There was a little bit of a learning curve with streams / topics, but it's one of those things that makes it worth it so much that there's no going back.

Search actually works, and there are many notification settings.

Microsoft Teams was giving me and my coworkers nothing but headaches until I found Zulip as an alternative.

It's a great alternative to Slack, but cheaper and more stable, and it scale with you if you are a startup

Researcher

It’s well-structured for multi-directional conversations.

Zulip is our main communication channel - we barely use e-mail any longer.

It's such high-quality software for it to be an open-source tool. Despite some advanced features requiring payment, you can get most of the fundamentals along with some really cool tools on the completely free plan.

I would love for it to be easier to organise larger teams, e.g. with documents and/or a clearer and more concise overview of chats and channel data.

The short list of presets do not include a "lunch" status, for example. And, it's difficult to see who is on or off duty unless they remember to specifically post that.

Director of Learning and Administration

Zulip is safe and secure for all users - especially for minors who need to contact each other in a safe environment, without the worry of external influences Zulip has been invaluable.

Channel threading is a great option, until you don't need it.

Works exactly how I hoped it would and has made internal communications simple and reliable.
