The best collaboration app ever

I've used Slack since 2019, across five companies. I even boomeranged, and Slack made it feel like nothing changed.

Somewhere in there, I used Teams. Once. "Collaboration software," they called it. What I got was four frozen faces, one "can everyone see my screen?", and a chat feature that felt like shouting into a void. Least collaborative hours of my career.

Slack, seven years later, still feels new:

- Search used to be my superpower. Now Slackbot just tells me the answer. That's the new AI paradigm, and it's a little scary how good it is
-Channels killed my inbox. No funeral needed

It followed me through four jobs and felt like home every time

Slack isn't a tool. It's a colleague I’m in love with, now.

Battery drainer

Latest update is killing the iPhone battery. 25 minutes of screen time consume 12% of an iPhone 17 pro max. Terrible performance. App is getting worse everyday

It feels sort of clunky. We use it for our office but it can be difficult to navigate.

Difficult and clunky to use
