A full version app for Android, by Galew.

Widgetshare is the most powerful and easy-to-use sharing app. It allows you to share a widget with a friend or loved one. When someone changes the picture on the widget, it instantly changes for everyone else. With Widgetshare you can create different widgets for all the important people in your life and fill your home screen with their photos. It works on iOS and Android platforms and even cross-platform. This means that you can send pictures to widgets on iOS and Android and they should appear on the other person’s home screen throughout the day. You can send pictures from your gallery or camera. You can also look back at your memories and download any picture you want to keep.
