Challenges & Opportunities

At the time of this project, Cronometer offered Free (basic features) and Gold (premium features) subscriptions for their app. While Cronometer was successful at attracting and aquiring Free subscribers, conversion and retention rates for Gold subscriptions were less desirable.

User Research

Through an indepth discovery process we discovered that Cronometer knew little about their customer segments, including motivations, attitudes, goals, and behaviours. Whether Cronometer was satisfying their customers' needs through their service offering and user experience (UX) was also largely unknown. To learn how to improve their conversion and retention rates it became a strategic necessity to conduct systematic customer development, as well as generative and evaluative user research.


When we had identified the most pivotal business and UX assumptions we devised our research strategy and methodology, including:

  • secondary analysis, including UX / UI heuristic evaluation;
  • a quantitative survey to understand user profile(s);
  • moderated indepth user interviews with pre-screened participants;
  • usability testing; and
  • training, managing, collaborating with Cronometer's team on the user research proccess.
