I have used versions of a team/group generator before (mainly TeamShake), and not only myself, but the students, love it! I like that it takes the bias out of selecting teams/partners. This app allows students to spin the wheel, which I've noticed cuts down on the complaining significantly. I also loved the option of putting the students faces on the wheel. I thought this was a fun touch and something my students would get a kick out of! I also really liked the idea that the app gave on the web store, of having it help with decision making. I know there are many times we struggle with various decisions (who gets to lead warm-ups, game we are going to play, inside or outside, etc.), and this would solve those problems for us in a fun and unique way!
