Yea I don't know of any. D3 planner is something I just recently found and I think it is rather new. How it currently looks is different from just a week or so ago when I first found it, so I think the author is still improving it.

Writing something that could take all the variables in to question would be pretty complicated I would imagine. Even character sheet stats like D3 planner gives you isn't an accurate representation of how a build will perform. You need to do actual testing and such.
