What is the best format for modern students. Students that are very computer savvy and some thing they can use on there phone?

Has any on used the Apple program face time with students that can not make it to class? I used it the other week for a student who was out with pink eye. It was like she didn't even missed class.

I have at least one student that just doesn't care. He/She just takes up a lot of my time to keep them on task. Any ideas?
