使用考勤計數迅速與默默承擔出席任何會議。
Use Attendance Counter to quickly and silently take attendance at any large meeting. A tap of the large green button will add to the running total - a slight vibration feedback gives you positive feedback that each tap was entered. Tap the red button to subtract from the total. When finished, tap the Done button and an email with the total count will be mailed to you.
