Brite looks like just what I want. But two things put me off. First. despite claiming a free tier, I was unable to create an account unless I bought the annual plan which just gave me three days free. Not enough to get used to such a sophisticated tool. Second, despite going through all the needed authentication, it was unable to connect my Outlook calendar. Without this, it's useless.

Oh, and third, I didn't see any way of communicating these things to the company.

And fourth, when you run the "newly-created" Windows app, it turns out it's just Chrome as a wrapper and you get a security warning that the framework it uses is out of date. Not exactly encouraging.

Fifth out of two, when you first start it up you get asked a lot of questions some of which have no applicable answers.
