# App Center

The ***App Center*** has tabs for upgrading currently-installed apps and browsing apps which are currently available (not that some apps are *not maintained* anymore to be recognized by a *not maintained* label).

To upgrade an existing app, simply click the ***Upgrade app*** button and open a vote to upgrade the app if you do not have direct permission to upgrade the app.
