ClaCal is an educational application developed by Benesse Corporation for iPhone. It is a free app that falls under the Education & Reference category. With ClaCal, users can manage their tasks and schedules together with their classmates and club members.

One of the main features of ClaCal is the ability to share schedules for homework, assignments, practice menus, and events among classmates and club members. Users can easily register tasks based on their timetable or date. Additionally, ClaCal provides a chat room feature where users can help each other and find solutions to any difficulties they may encounter.
