    Windows app. Visually it´s nice, but its movement between "folders" is not intuitive or i didnt like it. I didnt like it that we have to be online to access to it. I didnt like the option to introduce password everytime to access (i dont know if there is the option to remove it). In this case i´d prefer Standardnotes or Simplenote.
