You have childrens, and when they get sick, they have to take medecine several times a day... The Symbian Calendar allows to create alarms that are repeated each day, week, month, etc but not several times on a day... If you need to create alarms that recur several times a day you have to create them separately one by one...
With "seRalarms" you can create a reminder that is repeated every X hours (or minutes) and automatically creates the corresponding Calendar entries (and alarms). Also, editing an entry in seRalarms automatically updates or deletes the corresponding entry (or entries) in the Calendar.
