HOUSTON -

Two University of Michigan graduates believe they can help the nation waste less food with a new smartphone app. 

LeftoverSwap is free and available for apple devices.  It connects neighbors and helps them exchange their leftover food. Creators Bryan Summersett and Dan Newman came up with the idea one night after ordering too much pizza. 

Here's how it works. Download the app, take a picture of your food, and post it.  Hungry people nearby can look at that picture and offer to swing by and pick it up.

LeftoverSwap is not yet available for Android.
