This is a simple roll book application.
You can toggle the mark of cell in the sheet by tapping.
'P' as presence,
'A' as absence,
'L' as late arrival,
'E' as early departure.
(Of course you can customize these characters.)
In addition, you can export data as csv-file and you can import data from csv-file.
