In the Reports Overview you can view reports of your team members on a daily or weekly or monthly basis or you can also view reports for a custom date range, very easily.
You can also view the detailed report for the entire team or individually, and you also have an option to export those reports as well. You can hover on the stat name to see the logic basis on which the numbers are shown.
