You can keep attendance during the weekly Gathering and adjust it for prior weeks:
Tap the Calendar Icon on the top right corner in your home screen
Tap 'Attendance' on the left
Check the boxes for the people who attend
For a prior meeting date,
Tap the downward arrow next to the date
Select the date you wish to adjust attendance for
Check the boxes for that particular date
Keeping an attendance record is helpful for you to know which Members are attending consistently. You may want to reach out to those you haven’t seen in awhile!
