# Subtab Apps in Salesforce Classic

An app is a group of tabs that work as a unit to provide application functionality. Similarly, a subtab app is a collection of tabs that appears on the Chatter profile page. A subtab app can include both default and custom tabs.

### Required Editions

<table class="slds-table slds-table_bordered slds-max-medium-table_stacked slds-m-bottom_small edition"><colgroup><col></colgroup><tbody><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: Salesforce Classic</td></tr><tr class=""><td class="slds-cell-wrap" style="vertical-align:top;">Available in: <strong>Contact Manager</strong>, <strong>Group</strong>, <strong>Professional</strong>, <strong>Enterprise</strong>, <strong>Performance</strong>, <strong>Unlimited</strong>, and <strong>Developer</strong> Editions</td></tr></tbody></table>

Users can see different sets of tabs on the profile page depending on their context. Subtab apps are the various sets of tabs available on specific pages, such as users’ profile pages.

These default subtab apps determine which tabs display, depending on the user’s context.

 
| Subtab App | Displayed to the user when viewing... |
| --- | --- |
| Profile (Others) | Another user inside their internal org |
| Profile (Self) | Their own profile inside their internal org |
| Profile in Communities (Others) | Another user while inside a community. It’s shown only if Communities is enabled. |
| Profile in Communities (Self) | Their own profile inside a community. It’s shown only if Communities is enabled. |

End users can’t customize the display of subtab apps. Administrators can hide tabs within subtab apps using the Tab Hidden option in Tab Settings. Users can see tabs set to Default Off and Default On.
