Reviews for Sling: Employee Scheduling App

does almost everything you need it to do but one thing. on IOS offering shifts is instant while on Andriod across most devices you have to wait 10+ minutes per screen and even letter to type the individual you want to offer it too. this has been a problem for over a year at least when I first got sling. fix this one bug and it would be 5 stars.

March 2025: glitchy app doesn't always send notifications & sometimes not even an email. Seems to be more of a problem on android phones works well for a few weeks & then notifications become intermittent if any at all. Have missed shifts for work when they become available as haven't been notified in good time & someone else has taken. Sept 2025: still hit and miss if get notifications. Sort it out Sling still missing out on work shifts because of!!

Edited: decreased from 3 to 1 star. Getting notifications continues to be a problem randomly, despite having it set for notifications. We use Sling for scheduling our employees. It works well *most* of the time but when it doesn't, it really doesn't. We have had MANY instances where Sling stops working without notice, or it will reset everyone's settings or notifications randomly after updates. Our employees rely heavily on these, and it's a pretty epic fail every time these are reset

I've had it for 4 years because my job uses the app and I don't think it's been updated in that time. The same bugs persist and the app randomly stops working in the middle of messaging so you have to close the app and then retype your message hoping it will go through. It even affects my phone performance, after I close the app my phone lags for about 10 seconds. No other app does that.

Had the app maybe 6 months now and at first it was fine but now it won't let me upload any form of photo in newfeed it says "socket closed" after loading for a while...all the other managers and people can post photos regularly so it's very frustrating being one of the main manager and not being able to do that! Update: it's gotten worse now I can't see anyone's scheduled shifts under the full staff I have to Uninstal it and start over to get it to even load through Wed. Still can't post pics

Very broken app. As an admin, along with two other people, they receive notifications, and I don't. It would be nice if the settings actually worked since I do all of the scheduling. Trying to respond to employees through messages is a pain because typing bugs out all the time. If you send emails asking questions, they never respond but the company bugs you often to pay for yearly subscriptions.

Glitchy and hard to use. Once signed onto the app, it does not allow you to use other apps on your phone unless you force it shut. I also tried to download the app to my computer, but even though I clicked on the "download to other devices" tab, it still will not allow this to happen. Just started using this app for my new job and have already found it annoying and cumbersome at best.

I've had this app for about 2 years now and it's incredibly laggy and has a nasty delay om notifications. I've struggled to communicate in a timely manner due to not receiving a notification of a message for upwards of 15 mins after it was originally sent. I would not recommend this app for large scale communication. Lots of crashes and has even started signing me out multiple times in a day. Not worth the hassle for the fairly limited scheduling capabilities.

Find something that's not broken. I genuinely cannot stand this app and it's web version. It never registers my clock in/outs on time, I get messages on an INSANE delay, and I never get notifications on time. Then, on the browser, it constantly deletes my messages WHILE IM TYPING which is infuriating. File sharing is atrocious. Just find something else.

I get notifications sometimes and sometimes I don't. I've missed communication, it's almost flip a coin, 50% avg unnoticed.I've allowed permissions fully on my phone for the app and I've set on the app, notifications everything, still I miss almost half messages, no notifying on many of them, even when I have the app actively running. So if something is timely, I only see it when I bring the app to my screen. If it was impt, I didn't see it unless I hunt thru all that I didn't get notified of.

App is terrible for Andriod users. I have had to uninstall and reinstall multiply times because I just do not get notifications at all. It is fairly quick with picking up shifts, dropping shifts, and all that but the delay for notifications is insane. I either get a notification 30-45 min AFTER whatever happened has happened or (regualarly) I just don't get one at all. I have contacted support about this issue and they just remind me to make sure that ush notifications are enabled (They ARE)

It works, assuming I close and reset it several times a day. Otherwise it doesn't show messages, goes into infinite load screens, or won't send messages to others. It took me almost three months of fighting before I could finally get it to change my profile picture. It's a very frustrating app most of the time but when it works, it's useful.

It's great for scheduling and communicating, but it's hard to do so when I don't get notified of most of the messages I receive. I've updated, turned on my notifications AND have it notify my email, but I get neither. I have an Android, I guess it's more of a problem for Androids. Maybe enough reviews will get the notifications fixed for us, it's really starting to get annoying.

Sometimes it takes way too long for a schedule to load that I have to reset the app. The notification system is a joke. It gives you an option to receive notifications at set times. For example, you can make it so it reminds you that your shift starts in an hour or 30 minutes. But it doesn't matter because it sends the notifications whenever, it's never consistent. The recent one I received was 42 minute notification before the shift instead of it being an hour before.

The messaging on this app is atrocious. When typing a long message, the app slows down to a crawl and eventually freezes, forcing you to restart and type all over again. When trying to send a picture, there's a high chance the app will just close. And the notifications show up whenever they want. I've had people message me, only for me to read it a day later because the app never sent me a notification. I've had to give my coworkers my phone number if they actually want to reach me.

This app is severely neglected on Android. I use it for work and it's just not reliable. From calendar syncs, to notifications, to having to constantly refresh the feed. Not to mention if your connection is spotty or you're switching onto or off of wifi, it'll spam several little sliders to let you know. It uses a lot of battery for how little I get out of it.

💥💥USE 7-SHIFTS INSTEAD💥💥 I have an android and this app is absolute trash. My notifications show up when my actual phone notifies me but I open the app and they are nowhere to be found. Secondly, I wanted to put a shift up for grabs and the "..." feature in the upper right hand corner was simply not there. Even my boss was like, oh, weird. Thirdly, the platform in general is not easy to navigate through. Yeah, uh, just don't 🤣

I think the app is very useful and easy, but it keeps on randomly shutting off notifications and then I miss a bunch of info from work! I have to uninstall and reinstall regularly to get notifications back. I set up the backup of sending me email notifications, but even then I will miss messages for a few hours at a time. Super annoying.

Hit or miss. Mostly miss On Android it's just a nightmare. The code is extremely temperamental. One update works okay. The next one, you can't upload images. Then they fix that and you don't get notifications anymore. Then it kept signing us out randomly all the time. I've had it for about a month and it is broken more often than it works. Currently I can't attach photos again which is very important for my job. Works fantastic on Apple devices. So if that's an option for you do that.

Works great for scheduling. But for some reason they can't make an update that is compatible with android devices. It's one thing after another. The biggest issues is the fact that notifications DON'T WORK. Like at all. But the scheduling part of it is great. Everything else needs help ASAP. it's been like 9 months and notifications still don't work. I have to uninstall and reinstall app every week to get notifications
