Slack app reviews

  • Notifications Are Terrible 1/5

    By HughJazole
    Each day I seem to spend an hour trying to figure out how to turn on/off sound notifications. It should be a lot easier. I miss notifications every day. The app tells me my notification settings are incorrectly figured then leads me to my settings and bounces me back to Slack. Not a great app for group meetings online.
  • Slow and Need to Reset Cache a Lot 2/5

    By kabeji
    This app crawls, takes an extraordinarily long time to download even a single message. Also unable to see images after uploading them. A real pain when you’re part of a meme slack. Resetting the cache is the only way to clear this. Unfortunately slack is a necessary evil. At least try to make it a less painful evil.
  • Teams fan 2/5

    By m75wicker.....
    Seems like people like Slack. I like Teams. Not sure what Teams can’t do in place of Slack - unless it’s super complicated.
  • Slack 1/5

    By tloun
    It is too hard to delete all the messages from one group so that I can begin another one. I can’t seem to figure it out
  • The log in process is ridiculously over complicated and clunky 1/5

    By Taiga asdf
    As stated
  • Barely functional 1/5

    By j1234s
    It often doesn’t show all my channels work loses all the grouping information. It also freezes a ton and just generally is barely usable.
  • Very confusing 2/5

    By wildovenking
    The instructions for a number of items do not reflect what I see on my Slack app on my iPad. It is very frustrating that the instructions continue to show steps that do not exist in Help. kevin
  • Randomly missing notifications 2/5

    By ghxundt12
    Slack is the only messaging app that I’ve seen that randomly decides to not notify me about new messages. And the fact that it is used for work makes it much worse and impacts my career. Please avoid slack at all costs it’s a poorly made app that’s can jeopardize your business/career.
  • Poor accessibility 1/5

    By esterell
    I am a legally blind screen reader user, and when I used slack back in the spring of 2020, I remember it being at least moderately accessible. Now, as a workspace owner, I realize there are lots of features that I can’t access with my screen reader. Specifically, I can’t create channels, which is a huge issue. Please fix.
  • terrible app 1/5

    By LEO BSB
    I don't understand the hype behind this app. This like a messenger or whatsapp, it's just a chat app for work...
  • Was great now super glitchy and terrible after updates 2/5

    By Pirula37
    New version isn’t working on my fairly new iPad bc it no longer works on less than IOS13. Even on my phone, where I have latest IOS, pages take a million years to upload. Now super buggy and no longer serves.
  • Slack banners missing sender name 3/5

    By mannyy8855
    Is it just me or slack notification banners are missing the sender’s name.
  • Tired of incorrect notification counts 1/5

    By Asthanaut
    Why is the app always showing non zero unread notifications when there aren’t any ? Not great for productivity.
  • Good way to waste time 1/5

    By gfarca
    Quite disturbing interface for a chat app. There are hundreds of apps that do chat better and with human understandable interface.
  • Pretty good 4/5

    By berensona
    I like slack, but it feels like a Reddit knockoff. That said it’s great for group projects.
  • Love it! 5/5

    By atulya
    Feature for feature, Slack almost has all the features that Teams and other enterprise messaging apps have.
  • Constant sign in every few hours 1/5

    By Ax Zeronine
    Stop making me sign in over and over again.
  • Homeschooling 5/5

    By SBraswell-Pinson, AL
    New to me but liking it so far!
  • Remove user in app 2/5

    By Xmasbuns
    As an admin, I should not have to use desktop to remove users completely. Imagine if someone needs to be terminated immediately and as an admin I have no access to desktop, it’s terrible. And least do a gmail desktop view style - no one cares if UI is messed up. Just want to use admin features!
  • Audio alerts don’t work 1/5

    By TimToon
    There’s no point selecting alert sounds when the default system alert overrides it. This started happening after I updated, so I guess I learned not to do that again.
  • Great app 5/5

    By testing1567473
  • iPhone notifications 3/5

    By juan Carlos Sandoval
    Please fix this. I need a unique sound to work again for slack!
  • Annoying, confusing interface 1/5

    By hotturkey
    Who doesn’t have multiple email addresses nowadays? I keep getting sent to the wrong place. Grrr.
  • Doesn’t work properly on iPhone 6 1/5

    By They want a nickname
    Even “last compatible” does work right on IOS 12.5.5. Main screen is basically blank.
  • New User! 5/5

    By Sweet Dee☀️
    First time using a communicative platform like this with whole company. No complaints, however, I have listed some (non-critical) suggestions: -less steps to get to individual contact you want to send a direct message to - make those contacts easier to find. Greater efficiency. -increasing the size of the text (drop down menu, contacts, etc. -differentiating the segments within the app as well as making the titles/headers bolder/stand out more. Things just kind of hide within. Anyways that’s all!
  • Difficult to navigate and delete 1/5

    By K2MSU
    This app is difficult to navigate and delete. It forces you to join a channel to set up your profile.
  • What happened to your app? 3/5

    By Nika Name
    The version for iPad no longer allows websites to open! Says my browser is unsupported, even though it’s Slack.
  • Notifications 2/5

    By []]{%%^*=+%#}}‰
    Notifications don’t pop up on my phone. The app icon will have a number on the top right when there is a new message, but the app doesn’t alert me. I’m not the only one with this problem and I have double checked my phone’s notification settings. This is a COMMUNICATION app, and I don’t even get alerts for when I get messages. I’ll write a 5 star review when this is fixed.
  • Awesome 5/5

    By Spotless KTH
    This is such an amazing tool! I work from home so this truly makes communication easy.
  • Notifications 3/5

    By Redsue79
    Please fix the slack notifications. After update to iOS 15 slack is stuck on default notification sound. Extremely frustrating when you rely on the app for work every day.
  • Great for group communication 4/5

    By Smitty1400
    Pretty easy to catch on to. Could use a joint calendar function so groups can plan events while sharing one calendar.
  • Slack 5/5

    By axelr90
    Very good
  • Can’t delete members or workspaces 1/5

    By maxicurls
    Seriously. We’ve tried everything. This is a terrible app.
  • Frustrating lack of keyboard support 1/5

    By whargrove
    Slack for macOS really nails keyboard support. Slack for iPadOS falls short by miles — it’s not even close. Please improve keyboard shortcuts and support in this app! It is increasingly difficult to be productive using Slack on iPadOS because of it.
  • Bad 1/5

    By cringemastermega
    Not discord #bad
  • Messages won’t send out FTTT 2/5

    By Weibar
    Love Slack and couldn’t work without it. However the recent update causes some glitches when sending messages. My messages were ‘eaten’ from time to time.
  • DING!!! 5/5

    By Thebando
    SLACK Messages used to come to me with the ding sound. Since the update, ding doesn’t ding. it’s sounding a different sound even though ding is selected in my sound choices. I miss the ding : ( UPDATE: DING!!!! is back, and that’s a fact. Thank you slack!!!!
  • Reinstall required after changing jobs. 1/5

    By Euroclydon37
    I’m leaving a 1 Star to alert the devs. I use multiple workspaces. I also just transferred to another job. My previous employer deactivated my account, and now I can’t switch to any other workspaces or even remove this one. Seems like the request is failing. Probably due to an invalid auth token, if I had to guess.
  • Concise 5/5

    By C&JNCal
    Lessens emails & encourages concise comms.
  • RIP Slack 1/5

    By q00u
    It was getting slower with updates, and now has come to a stop. I'd say it's too bad my iOS version is too old to update, but from the recent reviews it sounds like the latest versions are broken anyway
  • Messages Frequently don’t send 2/5

    By Steven C.R.
    Love slack but the mobile version has messages that don’t go through after hitting send and sometimes the send button doesn’t work, the rate is too high to ignore
  • Nothing ever works 1/5

    By Josslyn Mulder
    Nothing ever works
  • Doesn’t work with most recent iOS 1/5

    By youknowitztrue
    Useless with the latest iOS upgrade. Bummer… had to uninstall
  • Very sluggish now 1/5

    By Hdrdude
    It feels like slack has consistently gotten worse over the years. At first it was always really fast and responsive. I would assume my internet is down before I would think slack was down. No more. On mobile it is extremely slow and sometimes simply cannot connect. In the browser there is lag while typing even on very fast computers. (Like chrome on newest intel MacBook Pro and also in chrome on windows). I don’t use it much in linux but I have not noticed issues there. Can you just revert to some earlier version of the codebase and stop developing. Or make sure you never make it less performant. Your major feature was extreme reliability and speed.
  • ZEOR STARS 1/5

    By sean_davies
    No longer works with my iOS, so, essentially useless now. Not going to buy a new phone. Probably going to move to another application.
  • Was great 1/5

    By Panamaniac444
    I wish I’d never updated. Maybe a month or two ago I updated to the latest version with the new style Interface and have had nothing but trouble since. It now marks channels as having been read without showing me if they happen to be open underneath the channel view screen. If I’m able to read the name before it disappears I know to go check the channel for new messages, but I don’t get even a full second after opening the app to do that and resort to channel hunting for new messages. I have to regularly restart the app because it slows down severely and becomes much less responsive. It was much much worse, but it’s still bad in the latest version. I wish the Slack team would focus on improving the core functionality of this app before adding more unnecessary features like voice and video that I already have better solutions for. I’d like to continue using Slack, it’s still great on the desktop, but the longer that the core experience remains like this, the greater the reason I have to switch to something better aligned with my use case.
  • Sluggish 2/5

    By TheIRI
    Ever since the latest big UI update, the app is super sluggish. I’ve tried restarting my phone and it helps for a bit but after less than an hour the issues return. Changing from one workspace to another is bad. Switching channels is bad. This has been one of My favorite apps for a long time and now it’s a pain to use.
  • Still waiting 1/5

    By DakotaMilkshakes
    Over a week and half and the alert tone issue isn’t fixed. Between this, the half-baked release notes and recent service issues, I sense a downward spiral.
  • It was good until.... 2/5

    By lovelesv
    Recently I've had the problem where I'll send messages and they will just completely delete and not go through. It's unpredicatable whether my messages go through or not. Now, today, I've had multiple issues where my messages won't send. Working on deadline makes it more stressful because I feel like I'm missing important information. Also, not sure if this has to do with the app or my phone, but my personalized notification chime is not working so it sounds like the rest of my notifications.
