QRAWR (the most challenging app to spell) offers a pretty awesome integration for youth ministry and younglife. The premise is simple… QRAWR sends you a roll of stickers and you apply those stickers in places of interest. When someone sees the sticker and scans it with their smartphone QRAWR opens up a posting platform for anyone to add discussion, photos, or dialogue about that location. With a bit of education and task to scan objectives you can create conversation for students over an event based moment or specific engagement. More info can be found here.
