While the dictionary definition is not the same, I think they are "similar" enough. Also, it's up to the user to define impact/importance, depending on their state of mind/ prioritization need. It's not a rigid framework.
I only tried your app on phone but it looks like you can't tap and add or drag things around. You always need to edit the numbers. Maybe the UX/UI could use some love?
Yeah. Click and drag is tricky in 3D, but I should add it to the 2D and list views though. I stopped working on it due to lack of any interest. I use it myself though.
