This is the one Ive been waiting for.

This is a terrific app. I teach at a community college and my students love this way of taking attendance. I am able to export my students info from D2L to dropbox and right into the app. I can generate qr codes and then each student gets one. Most of them store them on their smartphones. Then they just beep in every day. Awesome.
