You can customize your personal site with a new app or examine the contents of your personal site any time from your browser, providing that your site is supported by Microsoft SharePoint Server 2013 or Office 365, and depending on how your organization has set up the site.
To add an app to your personal site or examine your personal site contents, click the Settings icon at the top right of your Newsfeed, OneDrive, or Sites page and select Add an app or Site contents from the drop-down list.
The Add an app option lets you select an app from your local device or choose from a list of suggested apps. Site contents displays all content that comprises your site, including apps, newsfeed, libraries, and blogs.
Depending on how your organization has set up the site, the drop-down list from the Settings icon may show other options, such as Site Settings to let you update the look and feel, visitor permissions, and other aspects of your personal site.
