If you hate throwing away rotten fruits and veggies or food that has expired, let technology help you cut the waste. The free app FoodKeeper lets you take note of what you have in stock in your kitchen and pushes notifications when that item’s “freshness window” is about to come up. Since some foods have a longer shelf life than others, it can be hard to keep track. But with this helpful app (created by the United States Department of Agriculture), you can cut that waste. There are also tips on food storage and what needs to be refrigerated and what can be left on the countertop.
