We record our videos and design practice exercises using Qlik Sense Desktop and QlikView Desktop. That same download is available to you, absolutely free. (Yes, that's right, it is free and fully-functional.) This gives you the tools to actively participate in each learning module, by following-along with video demonstrations and performing exercise assignments.
If you do not have access to a computer which which meets the system requirements for Qlik Sense Desktop, there is an alternative option. You may use the Qlik Sense Business environment to import the data examples and apps (*.qvf files) which are provided in each module. The Qlik Sense Business environment provides a nearly identical experience to the Qlik Sense Desktop workflows you will see in our video demonstrations.
