This PDF gives step-by-step instructions on how to create a new contact in the portal, or web version, of Repfabric. The steps also apply in the mobile app. 

For Sync+, when you come across a name with a green plus, click the green plus, click “create new” fill in the fields you want and hit save. That contact will now appear with a purple business card and will automatically sync with Repfabric and appear as a contact in your mobile phone.
