APKGrabber is a tool that simplifies the process of finding updates for your installed apps. It will provide functionality similar to an app store without having to install the associated spyware that comes with it. This is a very useful app for those who want to run Android without an app store.

APKGrabber is a fork of APKUpdater. Big thanks and of course all credits go to rumboalla. I try to develop new features and maintain the software to stay available on latest android devices, but don't expect weekly updates.
