Synchronized Entities displays all entities that have been synchronized for each User/Device/Application combination. It shows the date/time the entity was last synchronized, the time taken to synchronize the entity and also displays the next time the entity is scheduled to be synchronized.
See the Mobile Framework Synchronization Guide and/or the Troubleshooting Touch Apps for more information.
To be able to advance the batch synchronization process for a specific Entity, User, Device and App Version it is possible to select the record and use the context menu Sync Now. This will not alter the schedule configuration but will synchronize the selected Entities, Users, Devices and App Versions combinations.
