I want to create one-time goals like “analyse my data per friday” or “plant my aunt’s flowers this week”. Is that possible? The “custom” goal option looks promising, but it’s inactive.
This is something of a known problem that Beeminder isn’t great at handling this right now. If there’s a way to make it a recurring goal, that works better - for example, picking one thing each week, or each day, that’s a “must do” and then recording that as your datapoint. See this post for more: http://blog.beeminder.com/mustdo/
If that still doesn’t do it, there’s also GTBee, which is admittedly lacking in polish but lets you create a todo list and then uses Beeminder to charge you if you don’t finish things in time:

Hope that helps - good luck, and let us know how it goes and if you have other ideas or feedback!
I have a goal that requires me to clear off my external todo list (at https://www.wunderlist.com/) a few times a week. I haven’t been using this setup long, but it’s been working for me.
