Food waste has always been a big issue and we all had the experience of cleaning expired food out of the fridge. And since U.S. labeling regulations don’t mandate an expiration date on most cosmetics, it is really tricky to determine its lifespan. The same wasting issue also goes to medications that are not common to go expired without being noticed. Zero was developed to help the user track and manage perishable products such as food, cosmetics, and medication. Our app would potentially assist users to reduce waste and save each user $120 per year from food and commodity waste.
