As a high school teacher with classes of 25–30 students, this app has been a game changer for classroom management. I use it every day to randomly call on students, quickly form pairs and small groups, and run quick warm-up activities — all without the awkwardness or bias of manual selection. The roster import and customizable options make it trivial to set up different classes and exclude students when needed, and the UI is clean and distraction-free. It saves me time, keeps student participation fair, and has even helped quieter students get more involved. Highly recommended for any teacher looking to make class time more efficient and engaging.
