Sync mode is a user configurable setting which affects the way {{UBIK }} client communicates with {{UBIK }} server. More specifically, it determines when and how the client fetches/commits {{UBIK }} content, or whether to have data communication at all.
== Possible sync modes ==
There are three/four different modes in {{UBIK}}. Here are their names and defined behaviors:
* Automatic: content is fetched/committed automatically;
* Manual Commit: content is fetched automatically; commit only happens when triggered by users;
== Mode switch & indicator ==

In the action bar of any {{UBIK }} client applications, there is a button for switching between the different modes. Upon clicking the button, a drop down styled menu would open with all the non-intermediate modes. Users can switch to any one of them by selecting them in the menu.
In addition, the mode switch button also serves as the indicator of the current mode.
