What is App Manager and what is it used for?

App Manager is a single desktop app to manage the extension panels for Adobe Creative Cloud applications such as Adobe Premiere Pro, Adobe After Effects, Adobe Photoshop, Adobe Illustrator, Adobe InDesign, Adobe Media Encoder

Using App Manager, users can control the installation, version upgrade and removal of the extensions in the Adobe Creative Cloud Applications. Just connect to the server and click on Install, Remove or Update button of the chosen Adobe CC applications, to either install or remove the extension panels. App Manager also monitors the application upgrade and notifies the user (with an Update button) if there is a new upgrade available for any of its Adobe CC applications.
