I think you're being slightly unfair. Of course it doesn't compare to full Emacs Org. Nothing does. But if you (like me) keep your life in Org and would forget to eat without it but sometimes have only your Android device, Orgzly has picked a highly efficient 1% subset. The dev is responsive and moves very fast too -- if you tried it more than a few months ago, you should give it another try.

I would not be where I am without Orgzly. Yes, I wish it was more complete. But given the very limited manpower behind it, it is excellent.

It's also better than any other similar app I've tried, even non-Org ones. So it's the best note-taking/todo/planner app for Android, and then the fact that it uses Org files behind the scenes is just a great bonus.
