I just added a signup form to planhack.com which would make it a public beta, however since only my friends know about this blog, that makes it a private beta. ;)
Basically planhack = split window day planner (calendar days on left, goals on right) with Vim keybindings
and modal editing. When you log in, you're in calendar mode and can
scroll days with "j" or "k" (or inverted T arrow keys), or weeks with "J" or "K",
to edit a day, use "i" or "e"
Just like Vim, escape will exit calendar edit and you can tab from the calendar to goals.
Here's a screenshot of it with some non-latin dummy text:
