The main difference between iClicker Classic and iClicker Cloud is that the polling results received via iClicker Classic are kept locally on your laptop or USB drive, whereas the polling results received via iClicker Cloud are accessed via cloud-based software that can be accessed with an Internet connection. Both iClicker Classic and iClicker Cloud can obtain student responses from either a student's personal device or an iClicker remote (as long as you have an iClicker base), depending on the settings you use. See the iClicker website for a comparison between the two tools.
