Hi, i see you need a mobile app ,both android & ios, basically for creating grocery shopping list.
It would have a secure admin backend portal for managing all purchasable items, their prices,locations,etc, also with promotions, favorites, recipes and videos for recipes, etc.
I can get this done for you very quickly, am a well seasoned developer with over 8yrs experience building apps and websites, you can be assured a job well done.
I do have some questions regards the barcode scanning feature...which bar codes are to be scanned? on physical items?
Would be great to hear from you so we discuss better.
Cheers.
