This is the iPhone Dock, which can hold up to 4 apps.
Hold your finger down on any app icon until they all start to ''wiggle''
First, you have to make room on your Dock. Drag & drop the unwanted app off the Dock.
While everything is still ''wiggling'', drag the Qcard icon and drop it on the iPhone Dock.
Press the Apple Home Button once to stop the ''wiggling'' and now you have Qcard on your dock.
We also recommend placing Apple's "Clock" and "Calendar" icons right above Qcard, which will provide a nice visual of today's date & time.
