http://www.searchlightnigeria.com/2013/10/app-that-allows-you-to-find-and-share.html You can exchange your uneaten half tuber of yam for beans by using a new app called LeftoverSwap. The app can also help people find fresh food in their city, or donate their uneaten food to others. LeftoverSwap is capable of making food products like bread, milk, burger, plantain chips, sausage, pizza, gari, yam, akpu and more; available to people who need them. The description of how the app works is as follows: snap a picture of your excess food, give it a name and click on share. A pin will drop on a map afterwards, hence allowing "Leftover Takers" to browse for their preference by geographical proximity.

Wow,cos right now i need to exchange my akpu with two indomies
