In the app reviews I read:
"Just kept sending me between two screens. The first told me to go to the widget on my home screen and when I hit the widget on my home screen to open the app, it took me right back to the screen that told me to go to the home screen. Never even got to try out the app!"
It looks like the User confuses a Calendar-Widget's shortcut on a Home screen with a Widget of the Calendar-Widget.
