The application automatically syncs to the server whenever the Mark as Done button is selected. To save your data in the middle of an assignment, you can either tap on the Slider Menu (3 horizontal lines on top right) and select Synchronize or simply tap the cloud icon on the top left. This will back up your answers while the assignment is still Open. You will also see a number in the cloud icon indicating that an inspection has not yet been synced to the server.
