Extract the APK from the tools installed on your phone
The tool is very simple: you just have to open the interface in order to access the list of apps you have installed on your mobile device's memory, or on a micro SD, and keep your finger pressed on the app from which you want to extract the APK.
Once you've done that, you have two options: you can either extract the link directly in order to copy it wherever you want, or send or share it directly from APK Extractor.
This lets you share the tools you download with your friends, so that they can access them directly through the link.
