Aroundly is an iPhone app that allows people to instantly share their pictures, geolocalized in a coral photo album. Just take your photos with Aroundly, instead of the default camera app: it will be uploaded to www.aroundly.com and automatically tagged on the map with its time and position. It's like a coral world photo album!
Anyone can upload new photos through his phone, comment them on the map and even directly delete pictures from others. It's like a wiki, but with photos.
