Attendance Monitoring - Day Centre

Hi, I manage a Day Centre for older people. Attendance can range from 1 day a week to 5 days a week (Monday-Friday) In order to track attendance we would need the functionality to identify which days individuals are planned to attend and the ability to record each day whether they have attended or not. This would then need to feed into a report that could display overall actual attendance verses planned attendance over specified period (say 4 weeks) Ideally on handset view it would be great to identify those people who are onsite that day with a different colour border or similar and also feed into the evacuation report, so we only see information for those who are on site and would need support in the event of and emergency evacuation.
