# Supervisor The Supervisor App is the place you go to examine your Call Center performance in more detail, especially over the previous days and months and years. The Supervisor App has all the charting and reporting tools you need to explore all aspects of ACD Skill and Agent performance within your Call Center, for as far back as you have data available. When you first enter the Supervisor App address (URL) in the browser, the browser checks LocalStorage to see if there is an active application key already associated with the browser, if so it will auto-logon, if not you will have to logon again. See Logging in and out for more details of how to log on to the Supervisor App. When the Supervisor App first loads, the Overview Tab is the first displayed. Other tabs include the Charts Tab and the Reports Tab. The navigation bar drop down menu provides a range of different configuration options. Go to Supervisor Options for more details of the different configuration options.
