Chef App & Chef Jeff
The system is two part: a mobile application, Chef App,
alongside an IoT device, Chef Jeff, that is put inside your fridge.
Chef Jeff takes a picture of what’s in your fridge every time you close it, so
that you can track what’s in your fridge when you are not home.
Chef App organizes your grocery inventory, allows you to
search potential recipes to cook with the ingredients you
have, and to generate meal plans.
Exploratory/Generational User Research
