Pikichat could be the next Snapchat. The idea behind the new photo app is ingeniously straightforward: Simply take a picture and then share it among a group of family members or friends.

Every time a person sends a new photo, it replaces the existing one. Group conversations take the form of the most recent photo added, with everyone possessing the ability to draw on the photo or add comments..
