phone app for barcode-to-textfile?

Hi all,

Does anyone have a phone app (pref. iOS) that will just scan barcodes to a textfile? All the apps I'm finding are shopping oriented or other special uses. I just want to replace our antique barcode scanner that spits out a list of barcodes as a text file.

Anyone have such a thing? Or advice on where to assemble the building blocks to create one?

Thanks
Ken
