I am the Founder of Groundscores, an iPhone app for people who have stuff at home they no longer need or see things in the street that might be of use to somebody else. You can snap a photo of the item, which is then geotagged and uploaded so that other people can find the item on a map.
I would love to get your feedback.
Is this something you would use? What type of person are you? Do you like finding things for free or do you like giving people things?
Loads of new features coming to the app soon.
Cheers for your feedback,
