FoodKeeper, the USDA’s mobile application, offers users valuable storage advice about more than 400 food and beverage items. Every year, consumers toss billions of pounds of food because of uncertainty of its quality or safety. The app helps consumers understand how different storing methods affect a product’s shelf life. The hope is to help consumers maximize the storage life of foods and beverages in their homes. In addition, the application has an integrated calendar that can remind users when items are likely to spoil. Users can search the application with swipe gestures or voice command. If a user cannot find information about a product, they can submit a question using “Ask Karen,” the app’s virtual USDA representative. The application is available for Android and Apple devices.

FoodCowboy is another app that takes care of large events. Originally founded by truckers and brothers, Roger and Richard Gordon, who as truckers worked to find food pantries or churches to donate fresh food that was turned down by retailers for appearances, like crooked carrots or too-dark eggplants. Often delivering after hours, they struggled to find organizations open late at night. And food was tossed out. The application lets donors enter information such as food type, temperature, quantity and description so food banks know what they’re receiving. Charities provide logistical information about where and when they can accept food deliveries. Recipients pay Food Cowboy ten cents a pound for donated food, which is a big discount, as typically, non-profits pay between 25 cents to 49 cents a pound for donations.

WasteNoFood is a California-based nonprofit web and mobile marketplace that connects people who have excess food with the hungry. Founded in 2011 by a seventh grader named Kiran Sridhar who, after learning about the amount of food wasted in the U.S., decided to help resolve the problem using technology to enable restaurants, hotels, convention centers, corporate cafeterias and sports stadiums to donate excess food to charities serving the hungry. There has been no efficient way for groups with excess food to donate to the millions of hungry Californians and Americans. Donors who wish to donate their excess food can sign up and post excess food as it becomes available. Qualified charities in the vicinity of the donors can claim the food. The charities are responsible for transportation and food handling. Levis Stadium, home to the San Francisco 49ers is among those partnering with WasteNoFood to reduce food waste.

Spoiler Alert connects people with excess food with those who need it. The app, founded by MIT Sloan MBA students Emily Malina and Ricky Ashenfelter last year, addresses food waste issues by helping organizations and companies manage their surplus food and organic waste by connecting them with organizations that can use them. For example, with the Spoiler Alert app, a store with the surplus vegetables can post what is available, and nearby food rescue organizations can respond and pick up the food in time to provide the still-fresh items to people who could use them. Eight Massachusetts-based food organizations, ranging from retailers, manufacturers, distributors and food-recovery non-profits, including the Greater Boston Food Bank, took part in a recent pilot program, and diverted 10,000 pounds of food in a six week period.
