What I'm Looking For…

It's a program/app that I can access on my home computer, my iPad and my iPhone, keeping them all in sync. It's mainly a notes program but you can use it as a journal or diary and also make "to do" lists with it. You'll can adjust fonts and you also have no problem exporting its data when you later want to switch to some other program. Oh…and I'd like password protection, too.

I've tried Evernote and it does a lot of that but it seems weak on the export capability and there doesn't seem to be any way of adjusting font size or page format, such as for lists. I could live with it but before I start pumping data into it, I'd like to see if there isn't something better. Anyone have a suggestion?
