HeadCount lets teachers log in with how many of their students will be attending Lunch or a field trip, or just attendance numbers. Originally written for a school that needed to tally up how many students would be attending Lunch, it could easily be used to count how many guests each employee will be bringing to a company picnic, how many guests will be attending a wedding, etc since the labels "Teacher," "Class," and "Number of students" can all be changed.
