Hi, I have a dance studio with 4 classrooms. I want to get an iPad for each classroom that will store all the music needed to teach. I was hoping that we could take attendance with the iPads as well. I looked at Bento, but it doesn't work with 4 iPads and the Filemaker Pro Server is too much money. Can anyone suggest anything else? Besides taking attendance I would love to have note and photos of each student on the iPad for the teachers to reference.
