I have three contexts in which I work. Work, open source, and personal.These three contexts have separate Gmail inboxes, separate Trello accounts, etc, etc. At the moment, I am also using multiple Beeminder accounts to set goals.

I imagine there are other use cases for wanting separate Beeminder contexts.

It would be handy if the iPhone app allowed you to add multiple accounts. As it is, I have added my personal account only, and check the web for my other accounts.
