MyAppSharer

To easily share the installation packages for any app, you can use MyAppSharer, a tool to send any of the apps installed on your Android device in a convenient, simple way. It has two transfer options: via the link to the app itself or via the APK installation file. Whether you want to send only one or everything you have, you can decide how to send it by clicking the corresponding option.

MyAppSharer works like this: mark the app and click on the share feature. From there, a menu will drop down where you can choose where to post the APK or who you want to send it to, although it's also possible to copy the download link to share on websites. You can also set up accompanying messages for the sent files.
