Install Manager is a free Android application from 4A that allows you to quickly uninstall multiple packages on your device. It is a useful utility tool for users who regularly install and uninstall apps on their devices. With Install Manager, you can easily select and uninstall multiple packages with just a few clicks, saving you time and effort.

In addition to uninstalling multiple packages, Install Manager also allows you to install any package that is already installed on the device, but under another user account, if your device supports this capability. This feature can be useful for users who share their devices with others and want to quickly install packages without having to switch user accounts.

It is worth noting that if your device does not support this capability, then your system's package installer may crash when you try to install packages under another user account. However, this crash is harmless, and you will still be able to install and uninstall packages as supported by your device. Overall, Install Manager is a convenient and useful app for managing your installed packages on Android.
