# About Apps feature Default ones are written and maintained by Ergonode, but it's also possible for developers to write their own. If you are interested, documentation can be found [here](https://docs.ergonode.com/apps2/).

You can install the same app multiple times if you need it. Ex: You may use different segments to synchronize or have different export file profiles. Instructions on how to complete the installation can be found in the menu below, as every app can be different. To edit an app, click on the kebab menu and select Edit, or simply left-click on the app field.

To edit, duplicate, or uninstall an app, click on the kebab menu and select *Delete app*. {% hint style="info" %} The duplicate option also copies all settings of the copied app. {% endhint %}

The next steps depend on the app, so please refer to a specific app description. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
