  1. 5/5Workplace Communications

    I love slack. I started using slack in January for my job, as our communications channel, between team members. This app has never caused me any problems. It’s NEVER: crashed, logged me out unexpectedly, had any technical problems, deleted any of my channels, failed in posting, or any other problems. This app is reliable, always functioning, never disappoints with the reactions and features to customize for your job specific needs, and in all ways shapes and form been hands down 100% real time. I love how i can change my profile picture, name, workplace info, choose privacy and notification settings, can set myself as away, and all my notifications come in once I’m active, have a dark mode enabled (this saves my tired eyes first thing in the morning) and an all the way around fun place to communicate with others. I don’t leave many reviews, and this is one of the only ⭐️⭐️⭐️⭐️⭐️ reviews I’ve left. Thank you for everything your team and developers have done to streamline our success. You’re amazing!

  2. 2/5One Step Forward, Two Steps Back for iPad

    The recent iPad App update misses the mark quite considerably. In some ways, it is almost as if Slack doesn’t understand its users. No longer easy to see all unread messages in one place - which was a feature I regularly requested for the desktop app. Now, the iPad app has been turned to be quite bland. Seems like the “Dark Mode” folks won the design argument; as the new app no longer supports the desktop or web app color themes; which now makes the iPad app incredibly difficult to know at a glance which team you’re viewing. Also frustrating are the 3 or so “Unread Direct Messages” you can see, when you tap “Show All” it takes you to the “Direct Messages” sidebar that sorts in its own way, with unreads strewn about. Also, Direct message addresses are much harder to read; too much text all clumped together. Unfortunate for the iPad app, Slack has taken a once very useful version (preferred as a second screen in some cases over the desktop app) and made it into a giant iPhone app. The iPhone app now also suffers from this Direct Message unread messages “Show All” problem. The only way to return some of the missing sort and see all DMs on the iPad app is to select the sort option of “by recent” but it does not group unreads. 7 years using Slack, and this is by far the most disappointing iPad app “upgrade.” Repackage the desktop app for the iPad and call it “Slack Pro” for iPad Pro users who use their iPad in place of a laptop.

  3. 3/5Implement a feature that allows NDA signers to use Slack safely on a personal mobile device.

    Authentication portals do not immediately or consistently appear upon opening the Slack app. It would be helpful to implement a feature that allows NDA signers to use Slack safely on a personal mobile device. It would also be beneficial to allow users to choose at what stage in the app the portals appear and what data needs to be protected and encrypted. Also found myself wishing to include different if/then/else modular scripts for the user to create a broader spectrum of security for Slack overall. One possibility could be encrypting data in the cloud and preventing mobile devices from storing any files or confirmed delivered messages from a not-yet-encrypted interaction sent via the App. Additionally, it would be helpful to add an accessibility feature that allows users to change the width of the scroll bar [for Desktop App] either by hovering over it and resizing it or by changing the width manually. Another useful feature would be a scrolling sensitivity setting that overrides Windows scroll settings while in the app but reverts back to Windows settings upon closing/minimizing Slack. Particularly for Desktop users: This would be particularly helpful for users whose mouse wheel has stopped functioning and need to quickly but thoroughly skim through several days’ worth of messages and posts. Implementing a workaround while waiting for equipment replacement or for Microsoft to address security procedure would be greatly appreciated."

  4. 3/5Texting but more complicated

    I used this app for several years at a past job. I would say it is like texting with a few small additions like the ability to tag people and notify them of something specific via an accompanying notification. That sounds useful until you actually use it and get tagged dozens of times an hour. Really this is basically just a messaging app with one problem. If you get a message from someone, or multiple people in group message, and you read it and think I will come back to this later and minimize the app when you come back later it is gone. It’s not really gone but it’s not still displayed as it would be if you minimize your texting app or WhatsApp. Instead you have to search for it. If it’s a message from one person you just have to search for that one person and sift through every message they have ever sent. If it has multiple people and you can only remember one you just have to search through every message that one person has ever sent anyone in your organization. If this were free I would say it is maybe useful as an alternative to using direct text messaging. If it costs anything I would say it needs some work. I could see it being good with some tweaks but it isn’t as of my last use which was in May of 2025.

  5. 3/5Does not work well with iPadOS 16

    When resizing the window of Slack, the changes to editing a post are lost. When pressing ENTER on the iPad keyboard, the message is not sent; you have to press a button. But this button is hidden behind a tiny floating language selection & dictation bar. I had to move it out of the way, and quickly hit ‘submit’ before the bar jumped back, a matter of milliseconds. I know Slack used to be a game company, but this is not the type of game I’m interested in playing :) I also find the app to respond slow on iPadOS, as if it’s not native but some kind of ‘HTML shell’ that doesn’t really bring the best of the native CPU/GPU capabilities. Lastly, I think they need to rework ‘search’. I would like to see a more clear distinction between ‘search everywhere’ and ‘search within the current channel or private conversation’. It takes ages to find something now. I also would like to see a more user friendly search query system (AND/OR) where I can add criteria. Right now it doesn’t ‘feel’ right - I know that doesn’t really help but perhaps they’d benefit from a larger user-acceptance phase for UX. Luckily it’s miles better than Discord, which although more powerful, is not easy to use or grasp.

Versions

  • 26.02.21

    Bug Fixes • We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.

  • 26.02.30

    Bug Fixes • We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.

  • 26.02.40

    Bug Fixes • The VoiceOver feature was glossing over certain details when announcing messages delivered via webhook. Going forward, its screen reading will be more thorough, helpful, and (dare we say it) accessible. • Returning to the main channel view after replying to a thread sometimes left a large, empty rectangle where the keyboard used to be. To put it in radio-friendly terms: We had a blank space, baby, and it was swiftly resolved.

  • 26.03.10

    Bug Fixes • iPhone-specific emoji (such as Animoji or Memoji) were failing to send within Slack. Please accept our sincerest apoloji. • Emoji were also occasionally not matching across desktop and mobile due to a localization issue. Our emoji interpreters have been working overtime to ensure this won't happen again. :ok_hand: :man-bowing:

  • 26.03.20

    Bug Fixes • One of our menus didn't get the memo when it came to turning notifications on or off for a particular thread. Specifically, when tapping into a thread and selecting additional options (...), "Turn off notifications" was always visible, even after notifications had been disabled. Going forward, all unsubscribe requests will be honored, and records shall be updated accordingly.

  • 26.03.30

    Bug Fixes • We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.

  • 26.03.40

    Bug Fixes • What's black and white and (re)read all over? Your Slack messages — when conversations stayed unread on mobile even after you'd read them on desktop. This riddle of a bug is solved in our latest update.

  • 26.04.10

    Bug Fixes • Tapping "View in Browser" on remote files added via API was appending a "/" at the end of the URL, effectively breaking the link. Let us never underestimate the power of one small character to topple even the most complex systems. • Batch image uploads were broken in canvases, forcing you to upload one at a time. Sometimes it's rewarding to take the slower, more deliberate path toward accomplishing a goal — mindfully connecting with each individual element and savoring the satisfaction. Sometimes you just need to upload 20 photos at once. This was the latter.

  • 26.04.20

    Bug Fixes • A little reminder as you go about your day: The world is a more unique place simply because you’re a part of it, and you’ve affected others in ways you can’t imagine. Oh, and no big changes to the app this time. Happy messaging!

  • 26.04.30

    Bug Fixes • All bugs that were fixed in this release were too small for the eye to see or too fiddly for human words to describe. Nevertheless, work was done, things tinkered with and the app became subtly better.

  • 26.04.40

    Bug Fixes • Bugs were squashed, performance was improved, work was done, and the result was good. Please enjoy Slack responsibly.

  • 26.04.50

    Bug Fixes • If you were removed from a private channel where you had a message drafted, a "1" would remain stuck next to Drafts with no way to clear it. We'll hang on to that draft for you in case you re-join the channel, but we'll hide the notification in the meantime. • Those using the VoiceOver feature were unable to select or play audio clips. All voices deserve to be heard in Slack — this update brings harmony to the app.

  • 26.05.10

    Bug Fixes • Don’t mind us — just making a few small adjustments to keep the app in tip-top shape. More to come soon. Cheerio!

  • 26.05.20

    Bug Fixes • Callout sections in canvases can now be edited on mobile. The ink never dries on a Slack canvas — revise to your heart's delight, no matter the device in hand.

  • 26.05.30

    Bug Fixes • If mandatory two-factor authentication was enabled for a workspace, but an owner or admin had not yet set up their 2FA, the login screen would disappear when attempting to sign in using a magic link. This type of vanishing act isn't the sort people pay to see. Behold, the prestige: Magic link login screens have reappeared in their rightful place.

  • 26.05.40

    Bug Fixes • Is there something strange in your neighborhood? iPad users were spooked to notice a ghostly white image in place of their newly-uploaded profile pictures. We knew who to call; this bug is now busted.

  • 26.06.10

    Bug Fixes • A little reminder as you go about your day: The world is a more unique place simply because you’re a part of it, and you’ve affected others in ways you can’t imagine. Oh, and no big changes to the app this time. Happy messaging!

  • 26.06.20

    Bug Fixes • In some cases, the Home view was loading in ever-so-slightly scrolled down from where it should have been. All the elements were still in view, but it just wasn't quite right. When you care about your guests, you want everything to be just so — and we do care about you — so please enjoy this very tiny fix.

  • 26.06.30

    Bug Fixes • If you created a custom filter in the Activity view to show only @mentions of your name, we were also displaying messages mentioning your keywords and user groups. Looks like there were some holes in that filter of ours. It's fixed now — don't mention it.

  • 26.06.40

    Bug Fixes • Ever have those weeks when it feels like nothing’s happening, but then you look back later and realize a lot of things actually were happening? This is one of those weeks for the app.

  • 26.07.10

    Bug Fixes • Is it something in the air? A certain je ne sais quoi that’s hard to put a finger on? The world seems brighter, music sounds sweeter ... what could it be? The Slack app has been updated, and we can neither confirm nor deny we’re responsible for any lightness that descends upon you.

  • 26.07.20

    Bug Fixes • Regrettably, some emoji were not rendering in canvases when viewed on the mobile app. If each of those little pictograms is indeed worth a thousand words, then we owe you a whole lot of characters under the current exchange rate. Might we submit that an app update is actually worth a thousand emoji? No? Fair enough.

  • 26.07.30

    Bug Fixes • Button, button, who's got the button? Workflows with Salesforce links certainly did not — those buttons couldn't be tapped on iOS. This update should button things up nicely.

  • 26.07.40 · 22 Jul 2026

    Bug Fixes • Minor tinkerings and tune-ups across the app. We appreciate your staying up to date! Let us know if you run into any problems by dropping us a line at [email protected].

  • 26.07.50 · 29 Jul 2026

    Bug Fixes • A little reminder as you go about your day: The world is a more unique place simply because you’re a part of it, and you’ve affected others in ways you can’t imagine. Oh, and no big changes to the app this time. Happy messaging!

  • 26.08.10

    Bug Fixes • Photoshop files pulled a disappearing act when shared in the same message as an image, leaving the image preview as the only visible element. This is now fixed, allowing PSD and PNG files to once again coexist peacefully.

  • 26.08.20

    Bug Fixes • HDR videos weren't playing back correctly on iOS. A world this vivid deserves an app that can keep up, and now ours does.

  • 26.08.30

    Bug Fixes • Dismissing the keyboard with a quick downward swipe sometimes resulted in the message input field getting stuck in the center of the screen. The keyboard and input will once again stick together like the best friends they are, moving in and out of view in tandem.

  • 26.08.40 · 26 Aug 2026

    Bug Fixes • No big fixes to call out this week, but rest assured, there will be more in the future. Not that introducing bugs is our aim, of course. But missteps, adjustments, errors, and corrections — these are the rhythms of life and the price of growth. We hope you’re enjoying the ride, no matter where you happen to find yourself at present.
