Here is a smart gadget that upgrades your fridge to reduce food waste. The Pallate comes with an app connected fridge camera and weight sensors to let you know when your items are about to expire. It automatically tracks what goes in and out of your fridge and how much you have left.
You can use your iPhone to track what you have and need to prepare recipes. The companion app comes with recipe recommendations based on what you have. It also helps you order groceries. This project is currently on Indiegogo.
