Sounds like they might be using HipChat self-hosted, not in their "Cloud" solution.

The question is why one would trust Atlassian to make decent software this time when hipchat is such a POS.

On a former team we were forced to use hipchat and their android client just nuked my battery. It was like night and day; remove the app and my battery lasts 24-30h; with it hipchat installed it would last 10 hours. This was a stock Nexus device btw.

I don't keep the client running all the time, but i do get notifications when I'm mentioned by name; haven't noticed any egregious problems.

I don't think Hipchat is a POS - it gets the job done - but it is lacking some features that I would consider to be fairly basic. (Why can't I edit messages except with the s// syntax? Why can't I do basic text formatting?)

I do agree with you on the lack of faith, though. Jira's text formatting is even worse than Hipchat's.

I am very satisfied with the Confluence cloud web text editor, but the Jira cloud editor is TERRIBLE. I wish they would bring the Confluence functionality to Jira.

Confluence annoys me; I don't want a WYSIWYG, I want to be able to just write some markdown without trying to wrestle all my formatting into a form that works.

My solution to this is to not use my phone for this stuff.

I only log into the site from a desktop browser. No point reading messages when I'm AFK anyway.
