This is for the LMS Canvas, that I heard about at PETE&C, as a solution that works well on iOS devices. More details can be found on their website http://www.instructure.com/
I've played some of the free Lumosity brain training games. Now they are accepting applications for teachers to get licenses for their class. There are more details and the research behind the move on the Lumosity blog http://www.lumosity.com/blog/were-helping-students-leap-ahead/
I've actually read through the entire application now. There are some components that are not feasible for my district based on policy. So, it might not be a match for your school, but it is still worth checking out.
