Check your GradeA settings to see where the attend.db file is
saved. In the previous videos, I used the Downloads folder. Quit the
GradeA application.

Copy the attend.db file back to your Dropbox/Attendance folder and
wait for it to sync up to the Dropbox servers.

Then on your iOS device, launch Attendance and choose the Restore from
Dropbox option on the Add/View tab. Press the Load Dropbox attend.db
button. And now the course and names have been added to Attendance.
