Attendance is a universal iPhone/Touch/iPad application. It allows you to take and keep attendance records. Its main intended use is for teachers to keep track of records for their classes, but it can also be used for meetings and group gatherings. Attendance runs on iOS 5.0 and higher on the iPad, iPod Touch, and iPhone.
