Yeah, Farm It!
This app is a way to allow Farmers, Farmers Markets, and Fruit Stands to market to their customers.
If you want to draw customers using the app, then you will just need to tweet using #yeahfarmit and provide your current GPS location. This app is set to search Twitter for tweets using that tag within a 25 mile radius of your current device location.
A twitter account account is required to tweet within the app, but not to search.
