From the developer:
NoteFlow is a different kind of note-taking app: you only get one note. There are no distractions, and the interface is clean and minimalistic. Your note is one place to write whatever you need. Once you're done writing, you can export your note to numerous compatible apps and then delete it from NoteFlow, keeping everything clean.
