Where your intranet shows the App Center depends on the installed theme. In a standard Confluence installation you'll find a link to the App Center in the topmost bar, the application header. Simply click on the button App Center and it will open and show all apps.

Inside the App Center the topmost category is called "My Apps". This section shows all apps you have favorited previously. This is useful if your intranet offers a wide selection of apps of which you are using only a small number regularly. By favoriting those, you have quick access to the apps you use most often. Additionally you can display those on any page within your intranet.

Depending on the installed theme there might even be a preconfigured section "My Apps" on your dashboard which shows your favorites.

To mark an app as favorite, simply click on the star icon.

To unfavorite it, click on the star icon again.

Depending on the way your administrator configured the App Center, there might be a section "Recommended Apps". These recommendations can be personalized based on your profile information. For example there could be recommendations based on your language, your division or other criteria. This helps you selecting important apps, but they'll only show up in your "My Apps" section if you favorite them manually.

This feature is optional, so if you don't see any recommended apps, it's probably not configured.

Depending on the way your administrator configured the App Center, there might be a section "Mandatory Apps". These apps can be personalized based on your profile information. For example there could be mandatory apps based on your language, your division or other criteria. These apps will automatically be added to your "My Apps" section and can't be un-favorised (There is no star next to the app).

This feature is optional, so if you don't see any mandatory apps, it's probably not configured.

Your admin can define if an app should be visible only for defined users depending on their profile information. If you can't see an app which is visible for other people in your company, this might be the reason.

You can export apps as a HTML bookmark list.

To display your apps on a Confluence page, select "MyApps" from the macro browser. No additional configuration is needed. The macro displays all those apps you marked as favorite on the page.
