App Manager - Android package manager (f-droid version)

App Manager began by merging the features of App_packages Info (formerly Application Info), ClassyShark3xodus, Activity Launcher and Watt into a single app with material design and dark mode to give a modern look and feel.

Features:

• Free and open source
• Material design (and a nice UI)
• No useless permissions requested
• Does not connect to the Internet without explicit permission from the user
• Display as much information as possible in the main window
• Lists activities, broadcast receivers, services, providers, permissions, signatures, shared libraries, etc. of any app
• Launch (exportable) activities, create (customizable) shortcuts
• Block any activities, broadcast receivers, services or providers with native import/export as well as Watt and Blocker import support (requires root)
• Revoke dangerous permissions (requires root/ADB)
• Disable any app ops, therefore any hidden permissions (requires root/ADB)
• Scan for trackers in apps and list (all or only) tracking classes (and their code dump)
• Generate dynamic manifest for any application
• View/edit/delete shared preferences of any app (requires root)
• View/kill/force-stop running apps/process (requires root/ADB)
• View app usage, data usage and app storage info (requires “Usage Access” permission)
• Apk file sharing (hence the use of a provider)
• Clear app data or app cache (requires root/ADB)
• Batch operations: clear app data, disable run in background, disable/kill/uninstall apps
• One-click operations: block ads/tracker components, block components by signature, block multiple app ops

...and other minor features such as installing/uninstalling/updating/enabling/disabling apps, displaying app installation info, opening on F-Droid, Aurora Droid or Aurora Store.

It basically combines the features of 5 or 6 apps that any tech-savvy person needs to use in order to have a life.
