# Applications

Applications are created and managed using the [**Application Designer**](/management-portal/designer/applications.md)**.**

**The Applications** tab is used for assigning one or more Application to the selected device configuration version. From this tab, you can:

* **Add or remove applications** from the device configuration
* **Update specific versions** of each assigned application
