It makes duplications of recent note by itself.

Thanks for getting in touch. Sorry for my delayed response.

Are the notes getting duplicated immediately when you create them, or are they showing up after you reopen NoteAway.

Also, are you using some cloud syncing? iCloud, or Dropbox, or something else?

Anyway, this shouldn't be happening so I'm sure we can get to the bottom of it, and I can hopefully find a fix. Just need some more information to understand exactly how and why this is happening and the exact circumstances of your usage.
