Is your one stop shop for all action related to controlling installed applications. After scanning you will have a searchable list of your installed apps. System apps are not shown by default, this has to be enabled in the settings. Some options may only be available (possible) if SD Maid has been granted root permissions.

The list of apps is by default sorted by their installdate, with the newest apps first. Each app entry contains the app icon on the left, the app name and their package name, as well as the total app size on the row end. The bottom of each app entry contains a set of tags with specific attributes an app may have.

  • System indicates that this app is a system. This may entail that it is priviledged to enhanced app permissions and actions regarding the app may be limited on unrooted devices.
  • Frozen the app is disabled. It may not launch by any means and it will not be visible in the devices app launcher.
  • Stopped the app has been forcefully stopped. It may not launch itself by any means until it has been manually launched by you.
  • Boot the app contains broadcast receivers that allow the applications to do work after device reboots. If the app has such broadcast receivers but none are enabled, the tag is slightly greyed out.

Some actions can be executed on multiple apps, some only on single items. To execute actions on multiple apps long press an app then tap to select additional apps.


Some of these actions are only accessible in the apps details which can be reached by tapping an entry in the list.

Run app

Launches the app.

Kill app

Tries to kill the app. Without root permission this is done with killBackgroundProcesses. How effective this is depends on the app itself, though generally it is not that effectives for killing system apps. If root permission are available, SD Maid will use the linux kill applets on all pids running under that process.

Force stop app

Tries to force stop the app. Essentially the same action as you have in the systems app settings. For an app do this we need root permission. The app can't launch itself until you open it once manually. This state will persist even if SD Maid is uninstalled.

Export apk

Tries to copy the apps .apk file from internal private storage to your public storages download directory. If the app is encrypted, then this action requires root, unencrypted apps can also be exported without root.

Freeze app

Requires root. Disables the app. The app will not be visible and can't start itself. It has to be enabled again to work. No dataloss occurs and this state also persists if you uninstall SD Maid. Any good app enabled/disabler app can enable apps that have been disabled with SD Maid and vice versa.

Move app

Requires root. If your device supports it, you can move apps from internal to external storage and vice versa. If an app does not want to be moved, SD Maid can force it, but the moved app may no longer run correctly. Excepted for the "force" option, this action is the same one as moving the app from the systems app menu. You can select multiple apps in the list and move them in batches.

Delete app

Deletes the app and it's data. This includes the systems uninstall process as well as actions similar to SD Maids Corpsefinder. Unrooted devices have to confirm each uninstall, rooted devices can batch uninstall without extra confirmation.

Reset app

Returns the app to it's install state. This will the apps data, but not the app itself. Similar to Clear data in the systems app settings, but it also includes extra app directories outside of default directories. that the system does not know about.

Receiver manager (autostart)

This feature requires root. It allows you to manage BroadcastReceiver. These are Android components that can react to specific events such as incoming calls, display state changing or plugging the device in the charger. Receivers can be enabled or disabled. Similar to disabling whole apps, these actions persist even if uninstalling SD Maid. Other root tools if well written should be able to undo SD Maids operations and vice versa.

BroadcastReceiver can listen to custom internal events (Intent's) as well as predefined system events. If SD Maid can attribute the BroadcasterReceiver as being register for a specific system event, the event type will be listed below the receiver name. Note that one receiver can be responsible for multiple event types.

Use this with caution, disabling items without knowing what you are doing will cause the app to malfunction in unforseen ways.

The most popular type of receiver people are usually looking for are ON_BOOT receivers which allow an app to do actions after booting/rebooting the device. While a badly written app can slow down device boots significantly if executes useless actions directly after booting, it is important to note that there are many legit use-cases for such a receiver. Specifically in SD Maids own case, it is required to restore the alarm for the Scheduler.


Include System-Apps

Whether SD Maid should show system apps in the list.

Keep desirable remnants

Some files belonging to an app may still be useful after uninstalling the app, e.g. photos or backups. Enabling this setting would cause SD Maid to, e.g. remove backups from TitaniumBackup if you uninstall TitaniumBackup.

Preload app estate

An apps estate is the collection of all the files and directories it owns across all detected storages. This is disabled by default to speed up the app search. Sorting by size will implicitly enable this. If app estate is not preloaded, you can still press "Scan" in the size box within an apps details.

Export destination

Where files (e.g. share app list or exported apks) are placed.

Double check apps

Some ROMs don't correctly update an apps state (e.g. enabled/disabled) (as returned through the PackageManager API). Enabling this option will cause SD Maid to double check the state of each app received through the API with the content of the packages.xml file. Unless you are have issues with exactly this, don't enable it.

Add shortcut

Adds an app shortcut to your home screen that directly opens the appcontrol page and refreshs it.
