If you just want to build your own iOS app you can fork mine (change the part the sends email to me as a back up):

I just create my own "refrigerator" by manually adding foods I eat (no bar code scanner or online database).

BTW, someone actually took forked my code and placed a version in the App store without ever asking me. I was sort of dumbfounded that someone would do this.
