I’ve been using Plickers regularly for large classrooms (around 50–60 students), and I really appreciate how simple and effective it is. However, I’ve noticed that when scanning answers in real-time, the app sometimes misses a few cards or takes longer to process when multiple students respond at once.

It would be great if Plickers could optimize the scanning algorithm or add a “double-check” feature that helps teachers verify which responses were not captured yet. This would make live assessments smoother and more reliable during class.

Has anyone else experienced the same issue or found a workaround for large groups?
