What sites do you know with the ability to create a personal schedule?

Question

User interface

Hello!
There is a client who does not yet have a final vision of the project. In the project, he wants to implement the possibility of creating a timetable for children. For example, on Mon from 10:30 to 10:50 a child plays music. From 16:10 plays football. With possible progress tracking. Or, for example, a schedule of classes in the gym with progress tracking.
Tell me, sites on which you can create a similar schedule. Interested in user interfaces.
Thank you.
