Mobile Synch is an older version of the Mobile Web.
Mobile synch lets you connect to your Open Dental data using a mobile device. View appointments, patient information, and pharmacies. Data is uploaded to Open Dental's server, then must continue to be synched with your database server to ensure content is up-to-date. Data cannot be entered using a mobile synch application. An active unique registration key is required.
As of version 14.3, the mobile synch occurs when you launch Open Dental; after the database is selected but before user login. This means if you are updating Open Dental, the mobile synch will not occur until after the update is complete.
