Usability
Interface 
User-friendliness/complexity of the tool´s interface
Easy to use.
Time efficiency Time needed for mastering the „how-to“ of the tool and a production of a task
High.
Interface language(s) The number of languages in which the tool is currently available/adaptable to
English only.
Respect for privacy Does the tool require registration? Who can see my data? Can I remain anonymous?
Medium (?). Wheel Decide does not have a proper privacy section, so this is difficult to assess. It uses cookies and displays advertisements, which seem to be tailored to user location. Wheel Decide employs Google Analytics on all pages, so choices created by the individual choice entry method will be visible to Google and the administrators of the website. It acknowledges users’ rights to data deletion and provides a form to request it. Wheel Decide does not state compliance with the GDPR. See more here.
Saving work for future use Possiblity to save your or others´ work for reuse/reproduction
Yes, users can access a Wheel Decide afterwards through a code.
Tailorability (If so, how?) Possibility of the tool to be used for a range of different activities (e.g. to what extent you can organize a project assignment with a central activity based on this tool)
Not much; users can simply input different options for Wheel Decide to provide a randomized outcome.
