In the early stages of mobile application development, mockups can be used to receive feedback from potential end-users. This richness of feedback is limited by the lack of interactivity and requires a lot of time for a more significant study population. The Klikker methodology aims to unite the designer, developers, and end-users in the initial phases of development by utilising modern web technologies and readily available � and interchangeable - design and analytic software. Klikker combines the collection of quantitative user behaviour and qualitative feedback from end-users on their own devices without additional effort from researchers. The method is intended to be deployed in the first few weeks of the development process.
