FIORI HCM My Timesheet and Approve Timesheet approval process

Hello experts,

I have read about My Timesheet app, and I noticed that workflow is not recommended way to manage approval process.

Can anyone suggest if the right way is for employees to work with My Timesheet to enter their attendances etc, and then manager to approve them via Approve Timesheet app.

Is it standard procedure since i noticed that people are not recommending workflows for these apps.

Thanks,
