Notification Options

I would like this app even more if there are notification options for my phone :) iPhone | Note 8

Developer Response ,

Hi there - notification options can be found by swiping in from the right side of the screen, then selecting Settings > Notifications. If you have any questions about this, please write us at!

Disappointed with the mobile app

Notifications are on, I have the mobile app set to notify me as quickly as possible with sounds and everything, but I still don’t get all of them. Even direct messages - I open the mobile app and I’ll see several messages from more than 12 hours ago which I was never made aware of. So annoying. If not for this, would have rated a solid 5 cuz I love Slack 💔💔 but mobile notifications are an essential part of the job

Developer Response ,

We totally agree - if mobile notifications can't be relied upon, what good are they? Please send us an email at; we'll be more than happy to investigate why this is happening!

Keeping us on the same page

So far Slack is helping the team coordinate and keep projects organized.

We’ve been using other IM apps but none of them are actually tailor made for work. 👍🏻
