Editors' Notes

Teamwork and communication made easy.

People need to communicate.


The approach for this app to our business is well placed.

All staff use it on a day to day basis to bridge the gap in 1 to 1 personal chat and group chat.

Learning is easy and we had 100% uptake on deployment.

App is fine to use on the 7 Plus, though me trying to connect to my slack workspaces form New Zealand takes ages..

I beg you please add a dark theme or something that’s easy on the eyes, especially in low light situations / night time.
