WerYoo ("where you," get it?) is a new free social network and app that lets you add photos to maps, share your photos with friends and get real-time updates on new photos and experiences near you.
To get started, you sign up for a free account via Facebook or a separate WerYoo account. After getting an account, you can take photos, add filters and view a live stream of photos taken near you as determined by your iPhone's GPS. Photos can be shared with friends or groups of friends, and photos can be searched by time and/or location. You can comment on photos and read comments people leave on yours. There is also a "hotspot" feature to let you or others comment on some particular part or feature of a photo.
Photos are shared via Twitter or Facebook, and photos from others you like can be shared via your camera roll.
