It's a convenient and simple app for keeping a bunch of services in one place, built specifically for Messenging apps. I like the flexibility it offers me to have different Slack channels, messengers, and calendars open at the same time, without too much commitment to the setup.
It's a brilliant coffee machine, which looks a bit like a SpaceX rocket with each coffee tasting brilliant. Each capsule has a barcode on the top of it, that the machine reads so that it can brew each coffee correctly. The capsules are more expensive but it's totally worth it!
