I use Kagan Cooperative Learning Structures so I thought this app would be perfect. I specifically wanted the team AND student selector feature to replace my spinner. Unfortunately, I don't think I'll use the app now that I've purchased and tried it. To me, the display seems backwards (shows the student selection first, then the team selection). This seems odd for structures I use a lot, like Numbered Heads Together. Also, the noise is awful and not customizable. If these issues were resolved, this app would be a daily part of my classroom.
