Archeor allows users to "catalog" the finds directly in the excavations, in the catacombs, where, obviously, there will be no data connection.
For this reason, one of the fundamental requirements of this application is that it has no connection with application servers to complete the stages of recording the find on your device.

The application is installed on the device and the user uses it to record "structured notes" relating to the cataloging of the find.
Before starting the recording of the finds, it is necessary to carry out the SYNCHRONIZATION of the Sites table present on the application server, in the presence of a data connection.
