Engage students using the devices they already bring to class

Reliably track attendance using GPS technology

iClicker Cloud uses GPS technology to confirm students’ locations when they "check-in" to class. Simply set the location and time of your class and let iClicker Cloud do the rest. Students are reminded to check in when class starts. An attendance report is created automatically.

Enhance learning with new question types

The new question types in iClicker Cloud allow you to send a screen capture as a target (heat map) question. Students answer by tapping on the image and you get instant results. Or, use the extended short answer question and allow students to respond with up to 140 characters.
