Blog or personal journal/diary recommendations?

I'm looking for a journal/diary for my iPhone/iPad/Mac, that will synch with all three if I wish, or at least allow me to move files between them.

If I can blog parts of it, that would be ideal, but I don't wish to auto blog all of it.

Must have a good interface and import of photo(s) from the day. I looked on the App store, and many of the good ones seem to be paid apps. Hence looking for comments.

Thanks!
