Ok so I am a huge fan of Countdown home delivery system

There are several things wrong with the interface to the system but we put up with that when it negates one wasting an hour and a half shopping!

The Problem.
1. They dont make a ipad specific app
2. The app provided only works vertically
3. by default ity uses the main camera to scan with

Question.
Is there away ,withing the os or settings to make software use the front facing camera?
This will allow for the placing of the ipad in the fridge to record items used directly into the countdown shopping list!
