If you know me, you’ll know I love my food. So when I heard about this app I got a little excited. Leftoverswap lets you advertise your unwanted grub so somebody nearby can call and collect it. It’s for people who hate the idea of throwing away food. All you have to do is take a photo, upload it, then wait for someone to message you. I think it’s a great idea. So if anyone has a chicken korma going spare, I’ll gladly take it .
