A Zone is a place to group related activity, for example everything to do with one project, client or person, so it's all in one place.
Adding items to a Zone
Move a recording (or other activity) into a Zone by selecting Move to Zone, then choosing an existing Zone or creating a new one. Any item that belongs to a Zone shows a folder icon in your activity feed.
Opening a Zone
Click the folder icon next to any item to jump straight into its Zone. Notes you've saved can also be reached from your home screen, or from the Zone they were added to.
