Periscope

This is one of my favorite new apps, if you can't really be there you can watch it live.  This app allows you to follow your favorites, your school, or businesses and watch important things as they unfold.  For my High School we have really jumped on board with students signing Scholarships and other big events that everyone can enjoy.  You have to option of watching it live and or going back to it which I really like.  If is a free app and you can follow as many or as few as you like, you can also go live and share your current situation with others that are following you.
