What did you miss in org-mode that your tool is going to have?
I can't think of anything, so I don't really know what benefits your tool provides compared to org-mode.
I've tried running emacs on android -- too much friction for simple tasks that should be quick.
I've tried mobile-org; the workflow is painful.
I've tried orgzly. It's almost workable. Maybe when it gets folding, and I can simplify my syncing scenario.
For the time being, I've dumped stuff into Mirakel and ownCloud Notes...will see how it goes.
